1988 Poison Open Up And Say Ahh Tour Rock Heavy Metal Vintage Band T-Shirt. Large Vintage hair metal band Poison tour t shirt from their 1988 tour "Open Up and Say Ahh". This is a perfectly worn in pre-owned shirt in great condition, especially for being 35 years old! This is what I'm assuming is a mens shirt, but it's 100% unisex. It says large on the tag, but apparently vintage clothing runs small, so please check out the measurements below Chest 21 in. Length 28 in.
