Cardboard interlocking alphabet set from 1924. Each letter is approximately 4" tall and 4" wide at the base. They have grooves so they can interlock to make words. On the base of each leter is a poem about an animal that begins with that letter. The 'x' is the only letter not original to the set-it was obviously created by a previous owner (see third photo). The letters all have pin holes from being placed on a bulletin board. Original booklet is included.
