SSPC oddity
 

Here's a card that's a bit odd. 1978 SSPC of Mickey Rivers. The big book shows these as being issued in sheets, but this one doesn't have the lines around the border. It's also full sized and appears to be factory cut.

Promo? Or were these issued some other way as well as in the yearbook and diary of a champion yankee book?
