A Child's Garden of Lifeforms in Our Galaxy was the name of a book whose front cover was designed by Doug Drexler for the Star Trek: Deep Space Nine episode "Time's Orphan". The book, that belonged to Molly O'Brien, featured several aliens from Star Trek: The Original Series on the cover.
The cover included illustrations of a Kalar, a tree bearing Kaferian apples, a pair of Ornithoids, Ruk, an Andorian, a Mugato, the Talosian known as The Keeper, a Tellarite, a Vulcan diplomat, a pair of copper-skinned aliens, a brown-skinned alien, and a Gorn.
