Exploring by Astronaut (1961)

Yet another book with great black and white illustrations. The artist is Helmut Wimmer who illustrated a number of books about space.

Branley, Franklyn M. Illustrated by Wimmer, Helmut K. Exploring by Astronaut: The Story of Project Mercury. New York: Thomas Y. Crowell. (104 p.) 1961.

 This early description of Project Mercury is illustrated as Helmut created some very detailed and unique illustrations to accompany the text.
