I am not quite sure of your question. The pin was issued for the fight with Corbett. Whitehead and Hoag had one of the patents for making pinback buttons. If you are referring to the name of the company presented on the back paper, I don't know who they were. My guess is either they were a pin maker themselves, or just a company that purchased the pins for this famous fight and gave them out as a form of advertising.
