He said that he had the original paintings used for the Dick Perez set of Mickey Mantle, Jake Peavy, Braun, and Dice-K. I had to ask how he came about getting them, and if he could send some scans of the paintings. He was more than happy to oblige.
He said that he bought all four at the Frank and Son's card shows in the City of Industry, CA. The person he bought the paintings from won them from a major auction house that acquired them from Mr. Perez himself. He bought the Mantle and Peavy cards on the Bay, but couldn't find any cards of the other two players.
He included scans of all four of the paintings he acquired:
I think it'd be pretty cool to see the actual paintings and the cards created from them together. If framed properly, the pairs would make wonderful conversation pieces. It's nice to see that these paintings aren't just collecting dust in some warehouse and that they are displayed in regular people's collections.
Good luck finding those other cards Vince. I wish I was able to help. But here's hoping that somebody might be able to give you a hand. If anybody happens to have extra cards from the 2008 Topps Dick Perez set of either Braun or Matsuzaka, (or both), and are willing to part with them, please e-mail Mr. Rosario at firstname.lastname@example.org.
