The Internet celebrated "Batman Day" over the weekend, and what a relief it was to finally, at long last, talk about Batman online! Anyway, now that all of you Bat-fans have gone back into your Bat-caves to secretly adore the Caped Crusader until this time next year, you might want to get a look at Prop Store's "Entertainment Memorabilia" live auction later this month in London (and on display now at Odeon BFI Imax in Waterloo, London) - which is full of props and costumes from the original 1960s series and the more contemporary films. Here are some of the highlights, along with what they're expected to fetch; if you're, say, the millionaire playboy heir to a Gotham empire with a few thousand dollars to burn, you can place a bid yourself online.
