Here's a cool item that Richard Wolffers Auctions offered in their February 1993 catalog: a Joe Jackson "Baseball Magazine" Advertising Display Piece.

Here's another cool uncut sheet from the hobby library archives, a 1973 Topps Test Candy Lid Uncut Sheet. This one was offered as lot 389 in Christie's East Sports Memorabilia Auction in October 1992.

Topps Magazine had a feature called Topps In The Field dedicated to news from around the collecting world; in the summer of 92, they included this piece about collectible pins, specifically the Hermes Ice Cream Honus Wagner from the Copeland Collection!

Probably a little moldy though…

There are folks willing to pay >20 #BTC for this.

I used to have a ridiculous 1978 Topps basketball collection: two complete high-grade PSA Sets, wax boxes, packs, trays, vending, display cases, wrappers, etc. But one thing that always eluded me was an uncut sheet, like this blank-back proof that Mastro auctioned off in December 2007.

Here's a historically significant ad TCMA placed in the April 1972 issue of The Trader Speaks—one of their first as a newly incorporated company that year.

Here's another cool item from Mastro's June 2008 Classic Collector Auction: a 1955 Exhibit Card Catalog.

Here are a pair of "1958" Topps Space Cards original artworks that Mastro offered in his June 2008 Classic Collector Auction.

It’s always amused me how hobby periodicals advertised on each other’s pages, almost like an endless loop of cross-promotion. So, I wasn’t surprised to find this Baseball Cards Magazine ad in the May 1982 issue of The Trader Speaks.
