This is a rare vintage single-stitched Hanes Grateful Dead T-shirt from the 70s, featuring a Blues for Allah design on a faded tie-dyed green and white background. The shirt was worn (to a few Dead shows, and a lot of other places) and washed many times, it is very soft and has a few holes, see photos. Some spots on the front, also wear to collar. See photos. Size is M, possibly a women's size M, it seems pretty small.
