I got two 1977 Pepsi Discs in a contest win from Johnny's Trading Spot. Mike Hargrove and Butch Wynegar. I have a couple of other discs already but these are my first that are still attached to the packaging.
here is a picture of a one, along with a Carty shirt, from a Pepsi wall display, from 4192cards.com.
