Two works by LS Lowry offering a view of the Thames at Greenwich are to be displayed at The Lowry in Salford, UK after being professionally cleaned.
Each of the pieces, a drawing and a painting, were stained from decades displayed in a busy family home - including what appeared to be ketchup.
Claire Stewart, curator of The Lowry Collection at the gallery, commented: "Lowry was a regular visitor to London, but his views of the city are relatively rare.
"The best known are his paintings of Piccadilly Circus, which are busy with cars and pedestrians. His fascination with waterways, however, meant he was obviously drawn to the Thames - and these works are a great example of that."
