This is for an original 1951 Topps Blue Back unopened wax pack that has been encapsulated and graded by PSA as NM 7. Similar to the Topps Red Back set with both sets containing 52 cards resembling playing cards, the cards were meant to be used to play a baseball game with each card having a designated baseball call like the 1968 Topps game cards. While Red Backs are known as Series A, the Blue Backs are known as Series B with both sets having the information printed on the front of the card under the player and the back looking like a playing card. Both sets were a part of Topps entry into the baseball card market but for some reason the Blue Backs are light years rarer than the Red Backs. Just a quick look at the PSA population report will show that over 482 Red Back packs have been holdered by PSA while only 58 Blue Back packs have been encapsulated. Even in unholdered form, Red Back packs are much more readily available than Blue Backs. This is one of 22 PSA NM 7 graded examples, and with people investing in graded unopened material, don’t expect many more to enter the marketplace, meaning the prices of vintage unopened material will only continue to skyrocket as one of the leading investments in sports memorabilia. A great looking rare pack and a must have for those starting pack collections on PSA’s set registry. This pack features PSA’s smaller 5 ¼ x 3 1/2 1/4 holder as opposed to the original 7 x 4 ½ inch holders. I also have another 1951 Blue Back PSA 7 pack on ebay if you are interested.
