The Giant Jam Sandwich covers from 1972 to the present,
story and illustrations by John Vernon Lord (set to verse by Janet Burroway),
first published by Jonathan Cape in 1972.
The book has been in print for 42 years. My first cover of 1972 (top left) showed a wasp perched on a stump (bottom right had corner). This was to show the scene as a prelude to the story without giving anything away. Future editions (when the covers have been designed by others) have tended to partly give the story away by showing later events.
