Beginner Books Are You My Mother & Put Me in Zoo

Two vintage hardcover children's books from the Beginner Books series: "Are You My Mother?" by P.D. Eastman and "Put Me in the Zoo" by Robert Lopshire. Covers show wear, edge rubbing, and discoloration/staining, particularly on the Lopshire book. Pages are intact with age toning. Plain back covers suggest early or book club editions.
