MEXICO OLYMPICS Set of 3 imperforate proofs affixed to Format International Security Printers Presentation Cards, plus the matching $1 imperforate proof miniature sheet (SG MS31), All in very fine fresh condition. We have been unable to locate a similar set for sale, but estimate that the current selling price of some specialist dealers for this scarce proof set of 4 items may be as high as £400.00 because Olympics is a strong specialist subject and these proofs are rarely encountered (image available) {P} (Start Price / Minimum Bid = £236.00)
