I found the picture below on page 136 of Bob Lemke's 2004 SCD Standard Catalog of Baseball Cards. (Bob, I hope it's okay to put this picture here...) You probably have a trimmed 1980 Exhibit card. The SCD says that these pictures were used on some original exhibits. I suspect, though, that yours is the 1980 version with the "An Exhibit Card 1980" trimmed off.
I hope this helps.
