Presented is one of the most legendary and sought-after of all Topps variations: The unissued blank-back card featuring Reggie Jackson in a Baltimore Orioles uniform with a New York Yankees team designation from the 1977 Topps baseball set. Jackson was traded from Oakland to Baltimore in April 1976, after Topps had already produced a card of him in an Athletics uniform for the 1976 set. He appeared in 134 games with the team, and 1977 would have been the first card set to feature him in an Orioles uniform. In late 1976, however, Jackson signed as a free agent with the New York Yankees. Topps had images of Jackson with the Orioles in their image files and planned for him to be included as such in the 1977 set in their first run of proof sheets. When he switched teams, Topps had to adjust accordingly and ultimately replaced his card with an airbrushed image showing him in a Yankees batting helmet and uniform. The final version of this variation is offered as its own lot in this auction, and the offered example represents the blackless version of this significant card. It is notable as it clearly features almost all elements of the final card! There are thought to be fewer than ten of the final version in existence (REA has only sold one example ever, which realized $66,000 in REA's Spring 2016 auction). The offered example is part of the eight color-process proofs used in the production of the card. Each is offered individually in this auction, and together they represent what may be the only complete color-process proof set of this variation extant. All nine cards have been consigned by the original purchaser from the 1989 Topps/Guernsey's auction. He recently commissioned the careful and precise cutting of these cards from the proof sheets, which resulted in the exceptional examples offered today. Graded MINT+ 9.5 by SGC. The card is hand-cut (by definition, as this card had to have been cut from a proof sheet). The card is absolutely flawless, with bold colors and sharp edges and corners. There are very few unissued proof cards of this type from so early a date. This is an extremely famous and very notable Topps rarity that would be a significant addition to even the most advanced Topps or important rarities collection and will come at a fraction of the cost of the final process variation! Opening Bid $2,500. Estimate $15,000+.
