A Rare Piece of Hobby History
At Tourdot Enterprises, we love discovering pieces of sports card history that many collectors have never seen before.
This is an original promotional poster issued by MastroNet Inc. Premier Auctions for their December 2002 Sports & Americana Premier Catalog Auction, featuring what was promoted as the 1952 Topps Baseball Card Complete Set – All 407 Cards PSA Graded NM-MT 8. The poster highlights one of the most iconic complete sets ever assembled, including legendary Hall of Famers such as Mickey Mantle, Jackie Robinson, Roy Campanella, P*e Wee Reese, Gil Hodges, Eddie Mathews, and Roy Campanella.
What makes this piece especially interesting is its rarity. These promotional posters are virtually never seen on the open market. Auction records are scarce to nonexistent, likely because so few were produced and most have remained tucked away in private hobby collections. A friend recently brought this fact to my attention, making me appreciate this piece even more.
I did not purchase this poster. It was issued by MastroNet in 2002 as a promotional item, and I have been its sole owner ever since. For nearly 24 years, it has spent most of its life protected in a poster sleeve. As shown in the close-up photos, there are a few minor imperfections from age and handling, but it remains a remarkable survivor from one of the hobby’s most memorable auctions.
After decades of collecting and selling vintage sports cards and memorabilia through Tourdot Enterprises, I’ve learned that one of the greatest joys in this hobby is continuing to uncover items that even longtime collectors have never encountered. I’m now ready to part with this treasure and would love to learn more about its history.
I’d love to hear from the hobby community: Have you ever seen one of these promotional posters? Do you own one, or know of another that has survived? Discovering something new (even after decades in the hobby) is what makes collecting so rewarding.
