A promo RIFF ROCK HOOLIGAN t-shirt from a WRIF Detroit radio station St. Patty's event. Seemingly rare. The year is unknown. Graphics on the front with nothing on the back of a green shirt. The shirt was made by Port & Co. and is 100% cotton. Sized (L) but check the measurements to make sure there's a fit. The shirt measures about 21" from PIT to PIT. It measures about 29" from the TOP to the BOTTOM in the back. It is in NEW condition as it shows no wear or tear or other signs of being used. No rips, holes, stains or fading.  Graphics are intact and vivid. Please check out the photos. NICE! Shipping is free in the USA. INTERNATIONAL SHIPPING is available.
