Sesame Street Wood Blocks is a set of Sesame Street alphabet blocks produced in 1975 by Playskool. The capital letters were decorated with pictures of Sesame Street characters; the small letters had pictures of animals and common objects.

The set includes minor characters that weren't often pictured on merchandise, including Granny Fanny Nesselrode, Poco Loco, Prince Charming, Roosevelt Franklin, Sam the Robot and Wanda the Witch.

The set came with a 20" x 30" colorful wall poster illustrated by Joe Mathieu, showing the Sesame Street cast out on the street, playing with the blocks.
