Here is a 1977 Topps Reggie Jackson #10 4-color film positive.  Acquired directly from the Topps Vault, it's color separation film positives are used during the printing and proofing process.  It measures the standard 2 1/2" X 3 1/2".  Perhaps a 1/1 item.

One peculiar aspect of this card is the airbrushing on Reggie's helmet - there still appears to be remnants of the previous logo (possibly Orioles) before the final NY logo was completed (and given a green helmet tint!).  Perhaps a nice complementary piece to the holy grail 1977 Orioles proof Reggie!

For authenticity, it is encased in the official Topps Vault holder with sticker seal, hologram on back of the lucite holder, and COA.  Regular issue card not included - just shown for comparison.

Please ask if you have any questions, and are looking for any other Topps test issues, proofs, or oddball player or team cards.  Thanks!
