A few nice pick up artists images I found:

These illustrations were scanned from "Spacecraft 2000-2100 A.D." by Stewart Cowley. I picked up the book from the Houston Public Library Book Sale. It is part of the Terran Trade Authority Handbook series, which wikipedia says is a set of books published in the late 70s about made up space worlds. Illustrations were provided by J.S. Artists, Ltd.
