Sesame Street Word Wheels is a 1972 Sesame Street activity book published by Western. The book contains three punch-out wheels, highlighting three "word families" -- Big Bird has the "at" words, Grover has the "en" words, and Cookie Monster has the "ug" words.
Each wheel has two cardstock pieces; when the pieces are assembled, you can "dial a word" by matching a letter of the alphabet in the main window. When the word is spelled out, a picture of the object can be seen in one of the windows. For example, Big Bird's wheel can spell out hat, cat and rat; Cookie Monster's shows pictures of a bug, a hug and a rug.
