100% cotton, sweatshop free (made by www.justshirts.ca). All T-shirts are brown, but there are three ink colours: green, pink, and shiny gold. Available in S, M, L. Cost is $17 (a little pricey but it's because they're sweatshop-free) plus shipping, which is between $2.75 and $8.50 depending on where you live.
