The miniature is from Reaper, the figure I use to represent my oldest (surviving) D&D character from back in 1981, Smirnoff the Huge and Ugly. There was one earlier character from my very first roleplaying session, but I don't even remember his name — he was blown to smithereens in that same session by being too close to an overly-curious halfling thief.
