Dave Parker game-used material card

I've got some Parker cards in hand though not one picturing him in his prime with the Pittsburgh Pirates, a team he won the National League MVP with in 1978 - to fill a hole in my award winners collection, I picked up a Parker 2012 Panini Golden Age Museum Age Authentic Collection material card for $2.

I was really looking for an autograph card but couldn't decide on the cards available - the color of the material caught my eye and I'd like to make believe the swatch was taken from something Parker wore in a game when he was a Pirate.
