The art of hand-colouring prints is a little-studied but distinct discipline, requiring skill and flair to be done successfully. Typically executed in watercolour or gouache, hand-colouring increases the impact of a black-and-white image, and can transform a print into something unique and personal. This collection comprises an interesting assortment of mezzotints and lithographs which have been overpainted more extensively than typical hand-colouring, meaning that many of these pictures appear almost as paintings in their own right.
