Mike Piazza Leaf Classic Art 1/1 Pre-Production Proof

Got this Mike Piazza 1/1 Pre-Production Proof from the Leaf Classic Art Signature Series. It's a pretty cool looking card with that green wave refractor style finish. Being a 1/1 proof makes it a unique find for any Mets or Dodgers fan. It's been kept in a one-touch case so it's stayed in good shape. Just thinning out some of my baseball card collection.
