This cult t-shirt shop on eBay looks mightily cool. I mean, you can actually get shirts with famous sci-fi writers' and philosophers' faces on. I've never seen a Sylvia Plath or Kurt Vonnegut t-shirt anywhere! And I like their (sadly limited) selection of old movie t-shirts. They've got several Louise Brooks ones and VINCENT FUCKING PRICE and Withnail and I and there's even a Wicker Man t-shirt. *grabbyhands* I'm so tempted by the Wicker Man, Caligari (shut up shut up shut up I need Cesare all over my tits thank you) and Siouxsie ones. Especially as the prices look affordable, too--although I'm always iffy about buying t-shirts like that without being able to inspect how poor the printwork is and whether they're those awful transferry ones that'll die after the first wash.
But dude. Their selection is much nicer than what I've seen in many cult t-shirt shops.
