The day after Dave's final show, his set was dismantled and pieces tossed into a waiting dumpster.
There are two entrances to the theater, and BOTH were used to dispose of artifacts and even audience chairs.
I suppose it's "nice" that CBS isn't being crass and offering the stuff at auction. Fans could get Yankee Stadium seats and other things when that place was destroyed (with a fake, a replica, built nearby).
The old NBC Letterman set, last time I checked, was on exhibit at the Museum of the Moving Image" in Queens. This one was too big? There wasn't a museum anywhere that would want an iconic miniature set of New York's buildings and bridges??
