The awesome Björk t-shirt, from Mädels Camisetas, a brazilian duo who make screen printed tees and sell them on Flickr. Their t-shirts have lots of music and cinema references. I particularly enjoyed the
milk cartridge taken from Blur's music video and the
Vote for Kane t-shirt.
If you haven't seen it, don't miss this music video from Blur,
Coffee and TV.
Here is a
flickr set with the full catalogue of Mädels Camisetas. Their prices are incredibly low (around $10 for girls and $12 for guys) and they accept orders through Flickr.
