Gateway Stamp Company is one of the world's largest distributors of autographs of famous sports and political…More figures. Gateway's business started when St. Louis Cardinal Lou Brock tied and broke Ty Cobb's sll-time stolen base record. Gate created a set of autographed envelopes from the city where he set the record and it was a smash success. What was to be a one-time effort turned into a successful business. Based in Florissant, they are now totally an Internet-based business.
