Boston: Houghton Mifflin, 1943, 1944. First edition - Two titles in the Lift-the-Flap Series - the outer half of each page needs to be opened to reveal where the babies are or which animals are being fed. Rather uncommon and fun, early books written and illustrated by H. A. Rey, creator of Curious George. Small format, 6" x 5 1/2", in paper covers with burgundy cloth spine. The front covers act as the title page. Set of TWO books.
