The World of Vintage Tee-Shirts:
7701 Melrose Ave.
Los Angeles California

This place has an amazing selection of vintage tees. The mostly second-hand tees here go from $40 to upwards of $200. If your looking for that so beat-up but so-cool T-shirt you will have hundreds to choose from.
My favorites included Alf, Dr. Pepper and a pretty beat up light blue Seton Hall tee.
