One of Australia's most prolific cartoonists Peter Chapman produced hundreds of comics over a two decade career including long runs on The Phantom Ranger and The Shadow for Frew Comics. Illustrations below are from a Chapman illustrated children's book, Minus Five and the Mountain of Gold, published in 1974, by Golden Press in Sydney. Minus Five refers to a deep sea analyser used to analyse the ocean floor. Author Victor Barnes also wrote another little golden book Barrier Reef Adventures of Minus Five, illustrated by Walter Stackpool.
