Rob Ryan papercut card featuring the message: 'Dear Adrian, Can we, shall we? Love ? XXX' found within the pages of a paperback edition of Mikhail Bulgakov's long-suppressed (in the Soviet Union), 1925 satirical novel The Heart of a Dog, in which the testicles and pituitary gland of a recently deceased man are transplanted into a stray dog! Hmm… I wonder if they ever did! Inscription on inside front cover also reads: 'Dear Adrian, Be my Valentine, Feb 13 XXX'. (Found Feb 2019).
