The Captain Marvel #2 Button has a 1.25 inch diameter and has Ms. Marvel taking up the mantle of the hero that gave her powers, Captain Marvel! Say, what ever happened to the first Captain Marvel? I asked Mrs. Gump and she told me that he was, quote, 'on vacation'. Hopefully he's enjoying himself out there! Anyways, the Captain Marvel #2 Button is what happens when a normal button is shielded by a Kree button...or something like that.
