Black and Blue tshirts are the only ones I buy.
For that reason, Vertigo has a lot of cool ones.
The lemon one from POPMART is still the best,
There is a blue one with the zooropa logo that is awesome...
but i really like the symbol ones...
you know.. the front just has three symbols on it
for Zoo Tv is was a Trabant, A Star, and a Babyface
for Popmarti is was a recordplayer, a shopping cart, and a (hmm... what was the third symbol. I can't recall)
for elevation there were two:
one had a suitcase, an elevator and an airplane flying around the world
the other had a suitcase, an apple, and a dove
for Vertigo it has a "V", a bomb, and a peace symbol
