We have a special appreciation and focus on the history of the game, which includes vintage and signed items from the 19th century to modern day baseball. 

The owner of The Bullpen, Joshua Mann, brings his 20 years of experience in signed books and manuscripts to provide the highest level of authentic material. All items are accurately described and meticulously authenticated to the highest standards. A full signed letter of authenticity from The Bullpen is included with every item.

We’re proud members of the Professional Autograph Dealers Association (PADA).
