Authentic Vintage Grateful Dead 1979 "What A Long Strange Trip It's Been" T-Shirt. Looks like a Men's Size Large, but the tag is missing. Shirt has artwork on the front & back. Artwork is by Stanley Mouse. The shirt's in good condition with some flaws, as shown in photos. This shirt's brand is unknown. I acquired it from a private collector who had stored it in a sealed container for many years. Since getting this shirt, I have also stored it in a sealed container. I have never washed this shirt.
