Remember this guy from the cover of OD&D Supplement I: Greyhawk? Well, I guess he survived this encounter with a beholder, as it looks like he later fights a dragon in the pages of the original edition of Advanced Melee for The Fantasy Trip.
I assume he has his dragon-killin' sword out, which he brought special for this fight, and his regular day-to-day killing sword is the extra one at his side.
