Vintage Tiny Pink Celluloid Zoo Animals

A rare set of tiny pink celluloid animals. The set of 5 include 2 elephants, 1 lion, and two other animals I'm unable to identify. Tiny, measuring approximately just 1" long x 5/8" at the tallest. Hand painted features, found in a tiny box from The Whitehead & Hoag Co of Newark NJ (box included). In very good condition with paint loss.
