I collect that series. Those are cardboard proofs, total catalog value $16. And with the stains, the pair might bring as much as $5.
Although there may or may not be a third stamp. He says you get all 3 shown.

PS: If anyone wants stamps like the ones in his other auctions, just ask. For the most part they're all cheap stuff.
