The bears that feature are aged between 44 and 98 years old - worn, stitched, and scarred, yet seemingly indestructible. Mostly they are anonymous, but several have celebrity status. Amongst thoseincluded are Nana, Jean Paul Gaultier's bear with the cone bra; Grayson Perry's 'personal god' Alan Measles; and Tomi Ungerer's bear, who inspired his famous children's book Otto.
