I’ve been looking for a childhood book that I loved from the 1960s or early 1970s, I think. I was about a prince who didn’t want to kill a dragon. The name of the prince may have been “Guy”. I think the dragon loved ice cream. The illustrations were only 2-color, maybe green and brown. Do you know what it was?
The Prince With a Hundred Dragons, by Malcolm Foster.
‘The Prince with a Hundred Dragons’ by Malcolm Foster, published 1963?
