EKOOSTIK HOOKAH Guster / Dr. John Poster By Mark ARMINSKI. Made in 1998, this poster is 35″ by 23″ and features both full posters for both shows and 5 mini posters. I think this was printed out and never cut up. Colors are vivid and sharp. These concert shows were in Ann Arbor in April on 2 different nights. Designed by Mark Arminski. Please see pictures for condition. Free shipping.
