On October 5-8, venerable auction house Christie's gets its hands dirty with Hollywood-style spacedust with 40 Years of Star Trek stuff. From a redshirt outfit from the original series to tables from Quark's bar, bad Kirk movie outfits (no hairpiece, thankfully) to Voyager ephemera, it's a treasure trove of Trek. There are 3-D chess sets and late-series tricorders; the Deanna Troi minidress at left is expected to go for $2,000-$3,000.
If you've got that kind of dough, you don't have to fly to New York to participate in the auction -- online bidding is available to people who pre-register before the Sept. 29 deadline.
PS There have been previous Trek auctions. I just couldn't resist the headline.
