NEDERLAND, Colo. — As a business opportunity, Nederland’s frozen dead guy is pretty hot right now. Well, technically, of course, he’s still frozen, packed in dry ice in a shed outside town, as he has been for going on 20 years.

But the concept and the rights to the name Frozen Dead Guy Days, the gleefully ghoulish late-winter bacchanal of ice and death and beer — that’s up for grabs. The Nederland Area Chamber of Commerce here in the mountains northwest of Denver owns the registered trademark to all things Dead Guy and has put those rights up for sale.

“It has grown out of our grasp,” said Blue Hessner, the chamber’s president. Mr. Hessner said that the board would consider all offers, with no pre-set price, and that depending on the buyer, “it could become a little more commercial.” He said discussions were under way with two potential buyers, but he declined to name any names.
