I love coffee mugs and tankards. I think having a "Tenkar's Tavern" mug would be a cool addition to my collection.Even if I never drink out of it I am certain it would be great for dice!
Which has me thinking...why don't we have an "official" Tenkar's Tavern supplement for OSR games? It could include maps, a bit of history and readers can submit an NPC to help populate the regular clientele.
That's just too good an idea to pass up :)
Of course a short adventure. "A Murder at Tenkar's" sounds about right. Characters would have to interview all those NPC in a D&D whodunit.
