We have a passion for the Sports Card hobby, especially in regards to graded vintage rookie cards, A Boston Red Sox fan from the start, and a childhood filled with junk wax cards, I've taken the hobby into a business, and have also self-published my own book about my journey through the world of Sports Cards.
