The 1-2-3 Sesame Street Playset was released by CBS Toys in 1984,  under the Child Guidance label. The set was re-released by Hasbro under the Playskool label in 1986.  This set is a re-creation of the "Sesame Street Apartments" playset made for the Fisher-Price Little People in 1974.
The 18-piece set includes two buildings, which, folded together, serve as a carrying case. The right side depicts 123 Sesame Street, with Ernie and Bert's apartment inside. Oscar the Grouch sits in his trash can, and can pop up at the push of a button. Big Bird's nest is also included. On the left side is Hooper's Store. Inside the lower level is the store while upstairs shows more of Ernie and Bert's apartment.
