I don't remember these little coin shape cards at all. I was only 13 years old at the time and a 7-11 was just down the street. Heck, I loved Slupree's. How did these cards escape my memory?
Below is a 1-1/4 " in diameter plastic disc featuring both a portrait and action photo shot of one of my favorite all-time Dodgers Alejandro Pena. The separate pics can be alternately seen by moving the coin slightly from side to side.
I can still remember the wind-up of slowest pitcher ever. Alejandro Pena's motion to the plate was like watching a cooling fan after the power had been turned off. He could literally lull batters to sleep.
