WhatsApp usBeneath the deep brown discolouration was a detailed nautical scene: The Monk of Liverpool, its rigging, sails and inscription still visible despite decades of acidic contamination and foxing.
For the owner, the watercolour had never been simply a picture of a ship. The vessel was connected to his ancestor, Commander John Monk, whose life spanned the closing years of the Napoleonic Wars and the great age of British sail.
Passed down through generations, the painting had become part of the family’s record of that history. As staining gradually obscured the image, there was a risk that more than paper and pigment would be lost; the visibility of a personal connection to maritime history was also beginning to fade.
In his first enquiry, the owner wondered whether the piece could really be considered fine art. For us, that was never the central question. Its significance lay in what it held: a ship, a family story and a remarkable chapter of 19th century seafaring. Conservation was not simply about improving the appearance of the watercolour, but helping that connection remain visible, understood and shared.
If a watercolour, drawing or family document has become obscured by staining, foxing or acidic mount damage, our paper conservators can help preserve both the artwork and the story it holds.

Conserving Maritime History
At a time when steam power was only beginning to challenge traditional sailing vessels, ships such as The Monk formed part of the commercial networks connecting Liverpool with ports across Europe.
Our client had researched the history of the ship and its owner in remarkable detail. Commander John Monk joined the Royal Navy in 1806 at just fourteen years old, less than a year after the Battle of Trafalgar. Over the following decade he served in the Baltic and Mediterranean, took part in military operations against Napoleonic forces and later fought during the Bombardment of Algiers.
One detail particularly stood out to us. During the bombardment, Monk suffered injuries that resulted in the permanent loss of sight in one eye. Despite this, he went on to command merchant vessels and continued a life at sea for many years afterwards. According to family research, he later marked the anniversary of the battle each year by raising a flag outside his home.

His final vessel was The Monk, built in Maryport and named after him. From this ship he traded between Liverpool, Dublin and Mediterranean ports, carrying goods through waters he had first known as a naval officer. The watercolour remained within the family alongside documents and memorabilia connected to his life.
This context gave the treatment a particular significance. The ship emerging from beneath the staining was not an anonymous maritime scene, but part of a family’s record of an ancestor’s extraordinary life. Conserving the watercolour meant stabilising the paper and reducing the discolouration, but it also meant helping a personal piece of maritime history remain visible.
Historic Watercolour Risks
Watercolour paintings of this period are particularly vulnerable to environmental damage. Paper naturally absorbs pollutants and moisture over time, and when historic works are mounted on poor-quality acidic backing boards, the degradation products migrate into the artwork itself. This often results in widespread yellowing, brown staining, foxing and embrittlement.
In this case, decades of acidic contamination had left the image heavily discoloured. The once-light sky had become a dense brown tone, the sea had darkened considerably, and much of the subtle modelling within the sails and background had become obscured beneath staining.

Assessing the Watercolour
Following arrival at our studio, our conservators completed a detailed examination. The primary issues identified were:
- Extensive overall discolouration caused by acidic migration from a historic card backing.
- General staining and embedded contaminants throughout the paper support.
- Surface dirt and accumulated pollutants.
- Adhesion to the secondary backing material.
- Localised fading that could not be reversed through conservation treatment.
- Structural concerns requiring additional support following backing removal.
Although the image was still legible, many of the finer details that made the vessel identifiable had become obscured beneath extensive discolouration. Preserving those details would be essential if the painting was to continue serving as a visual record of the family’s connection to John Monk.
Our assessment concluded that the backing should be removed, the paper washed to reduce contaminants and discolouration, and the artwork subsequently relined onto an acid-free support for long-term stability.

Watercolour Stain Removal & Stabilisation
Treatment began with careful surface cleaning to remove loose dirt and atmospheric deposits from the paper. Once the surface was prepared, the historic card backing was removed. This was one of the most important stages of the project, as the backing had been the main source of acidic contamination and had contributed significantly to the overall brown discolouration.
The watercolour was then treated through controlled washing, allowing staining and ingrained contaminants to be safely reduced. This helped improve the tonal balance of the sheet and reveal more of the original detail. Further testing guided the safest approach for reducing residual staining without compromising the delicate watercolour, ink and gouache pigments.
Once the staining had been reduced, additional washing and stabilisation treatments were carried out where required to support the long-term condition of the paper. As the removal of the old backing left the original sheet more vulnerable, the artwork was relined onto acid-free conservation-grade paper, providing structural support with materials compatible with the original work.
Finally, the watercolour was carefully pressed and flattened before being prepared for reframing with conservation-grade materials, helping to protect it from future acidic damage.
The Results
The transformation was significant. As the discolouration was reduced, details that had been hidden for decades began to re-emerge. The rigging, sails and inscription became clearer once again, allowing the family to reconnect with a vessel that had once sailed under the command of their ancestor nearly two centuries earlier.
Looking at the restored watercolour today, it is easier to understand why it remained in the family for so long. What survives is more than a maritime painting. It is a tangible connection to a British naval officer who sailed through the final years of the Napoleonic Wars.
Conservation cannot turn back time, but it can help ensure that the stories embedded within an object remain visible. In the case of The Monk of Liverpool, that meant preserving both a historic watercolour and a family’s connection to a remarkable chapter of maritime history.
