Here's another historically significant Topps contract, signed by Tom Seaver on March 8, 1969 - the spring of the year the Amazin' Mets would win the World Series!

Here's an original New York Yankees payroll check signed by Thurman Munson—a tough and highly sought-after autograph from the beloved captain.

If you're a Cubs fan, how's this for a cool hobby cave display piece, a 1945 World Series Ticket Sign from Wrigley Field?

Leo Durocher managed the Giants to a World Series title and pitched sugary cereal to kids! Mastro offered this one in their November 2001 catalog.

In December 1953, Topps cut Willie Mays a check for a whopping $50 to appear in their 1954 baseball card set—less than what a torn copy of his card is worth today.

Hobby and NBA history from Mastro's December 2007 catalog, Pete Maravich’s 1970 rookie contract with the Atlanta Hawks. A groundbreaking $1.5M moment in sports history.

Here's the original artwork Dick Perez painted for the 1989 Donruss Mike Greenwell #1 Diamond Kings card.

Here's a cool uncut sheet I ran across in the June 2008 Classic Collector catalog, a unique 1968 Topps Non-Sports Multi Issue Full Uncut Sheet of 132 cards.

I dug into the allure of the Topps Dynamite Magazine Panels in the 5th part of my deep dive into 1978 Topps baseball cards. So, I was pleased to find this 1978 Eddie Murray RC insert while perusing the September 1996 Oregon Trail Sports Auctions catalog!

I've shared plenty of vintage advertising signs before, but I think Stan Musial deserves more focus since he had fewer major card releases than his peers. Here's a great Rawlings die-cut sign from the mid-1950s.
