I recently bought a watercolour painting described as the 'Old Bathing Houses, Liverpool'. The description on the reverse (which I've also scanned below) says 'taken down in 1811', and then signed by, what looks like, 'J. Pervise, Oct. 1821'. He may be the artist or the original owner of the painting?
I've attached an extract of George perry's 1769 map of Liverpool [LRO] - the Baths can be seen on the extreme left-hand side where the river wall kicks back to the main shoreline. They were located in the middle of the later built Princes Dock quayside, Bath Street.
