This first survey exhibition of collage ever to take place anywhere in the world spans more than 250 works, from 16th-century anatomical flap prints to computer-based images. It includes work by amateur, professional and unknown artists; collages by children and revolutionary cubist masterpieces by Picasso and Juan Gris; nineteenth-century do-it-yourself collage kits and collage films of the 1960s. Highlights include a three-metre-long folding collage screen purportedly made in part by Charles Dickens, and the only surviving original source photographs for Peter Blake’s collaged cover for The Beatles’ Sgt. Pepper.
