Tim Biskup, Chris Edmundson, & Greg Long are the creators of Gama-Go, an illustration fashion label based out of San Francisco. They started out with 6 designs on tees (working out of Long's basement in late 2000), and have since expanded their range to include everything from clocks, pillows, books, toys and hoodies. They have created enduring characters in their designs like Dirty Bird, TigerLily and Yeti (Shibuya Yeti pictured).
All their designs are limited edition. You can get Gama-Go gear in the USA, Canada, Venezuela, Singapore and dotted across Europe - its even in Australia (try MunkyBizness at Newtown or Paddington in Sydney, or Pocket Space in Hobart, Tasmania).
