New to this site. I have been collecting vintage sports cards for years. Recently, I began collecting vintage non-sport cards. I purchased a few 1975 Shock Theater cards on Ebay. I found some information about them on the internet, but i still have an unanswered question. I found a site that shows what each card looks like in the 1975 test set. All of my cards were in those pictures, except one. It is Card #1. The back of the card includes: "1970 EMI Film Distributors" and the front has "But I ordered a Vanilla Shake!". The description on Ebay says that it wasn't part of the original set. So, my question is - "What is this card?" Appreciate any help I can get on the set - the history interests me.
