After Stanley Spencer's death in 1959, his friend, Henry Trivick, was commisioned to create a series of a few limited editon prints, taken from Spencer's original work. These were sold at the Spencer Gallery in the village of Cookham, Berkshire. This print (created by Trivick at the Friary Studion in an edition of 76) is taken from Spencer's pen, ink and chalk self-portrait, currently held by the Tate Gallery. Another example is on display at the Spencer Gallery.
I'm a massive fan of Spencer's work and try and snap up the Trivick lithographs whenever I can. They're eminently collectable. Sadly, this doesn't happen as often as I would like.
