Just a quick cover today before I miss more "blogging" days. Franklyn Branley wrote many, many children's science books. He often worked with the illustrator Leonard Kessler, whose drawings are wonderfully simple.
Branley, Franklyn M. Illustrated by Kessler, Leonard. A Book of Mars for You. New York: Thomas Y Crowell Co. (56 p.) 21 x 23 cm.
It outlines what is known currently about Mars and our exploration plans. Includes drawings of spacecraft, manned exploration of the Mars surface and reproductions of some of the early photos of Mars.
