Prop Store, an expansive operation based in Los Angeles and London whose focus is right there in its name, has announced it will be hosting an auction of entertainment memorabilia during August 26-27. The shop has "over 25,000 combined square feet of archived props and costumes," meaning the upcoming auction's 870 lots spanning two days will likely have something for everyone who is looking to buy--and also willing to spend. Information to bid, register for phone bidding, or to register for absentee bidding can be found on Prop Store's website. There's also a link there to watch the auction next month.

The catalog for items is available both as a physical print book to purchase for $45 or as a PDF that can be freely viewed now. But if $45 makes you balk, this auction may be too rich for your blood. Just flipping around the 251-page PDF, items that caught our eye include a model of the commercial space-tug Nostromo from 1978's Alien, which was used for principal filming. The 11-foot model is estimated to fetch $300,000-$500,000. Remember that all items require a shipping rate, and some items come with a special, more premium shipping rate. Fortunately, payment plans are available.

Also available is a Starfleet tunic from the pilot episode of Star Trek: The Original Series (expected to fetch $4,000-$6,000), but be forewarned that "memorabilia" is also code for something that isn't mint and is likely to have a fair amount of production wear and tear—this tunic's "velour top was originally blue, indicating that it was worn by science officers, but turned mauve after repeated cleanings." Fortunately, in this case, the metal zipper runs up the back, which includes care information for the garment. From Star Trek: The Next Generation TV series, a screen-matched Borg cube hull section display, in a clear acrylic case, will be for sale--estimated to run $3,000-$5,000.
