Big Head Todd and the Monsters concert posters by Scrojo, who has a large number of concert posters on sale here.
And a few more links:
1. I hadn't heard of dieselpunk before. Via.
2. Geisha with octopus and headphones.
3. The logo is pretty ugly, but the review of the surf tee is pretty compelling.
*Previously: $1000 headphones anyone?
*Buy geisha toys at eBay.
