For fans of vintage Saturday Night Live, here is a Child Small T shirt featuring Mr. Bill.  

Some history: Mr. Bill is a clay figurine star of a parody of children's movies shows created by Walter Williams in 1974. The Mr. Bill showing got its start on Saturday Night Live as a series of Super 8 films sent in response to the show's request for home movies during the first season. Mr. Bill's first appearance occurred on the February 28, 1976 episode. After five submitted films, Williams became a full-time writer for the show in 1978 and wrote more than 20 sketches based on Mr. Bill.

The T-shirt has some stains and holes, so not in the best shape.  Email me if you have questions.  Thanks.
