I got a tip from my friend Cory that 80sTees are selling these awesome looking Blackmoor T-Shirts with the image from the cover of D&D Supplement II. The website offers this description of Blackmoor:
Blackmoor is a campaign setting for the fantasy role-playing game Dungeons & Dragons. It originally evolved in 1975 as the personal setting of Dave Arneson, the co-creator of Dungeons & Dragons, first as a setting for Arneson's miniature wargames, then as an early testing ground for what would become D&D. Blackmoor is the longest continuously played fantasy role-playing campaign in existence. It is a mysterious land of sword and sorcery mixed with relics of highly advanced technology. Everyone will immediately know you are a fan of the classic role-playing game when you wear this 80sTees.com exclusive Blackmoor Dungeons & Dragons T-Shirt!
These T-shirts come in black or natural color and are officially lisenced Dungeons & Dragons T-shirts from Wizards of the Coast.
Do you have any Blackmoor branded clothing yet? :)
