The Worldly Philosophers by Robert L. Heilbroner. No mention of cover designer. Simon & Schuster, ©1953, 1961.
Physics and Philosophy: The Revolution in Modern Science by Werner Heisenberg. Cover design by Guy Fleming. Harper & Row, NY. ©1958, this edition 1962.
This last one isn't on philosophy, but was found in the same section:
The Enduring Art of Japan by Langdon Warner. Cover design by Roy Kuhlman. Grove Press, NY. ©1952.
Not sure what was erased in that upper right-hand section—original price, perhaps? Instead of photoshopping it out, I decided to leave it be.
