3-D Grateful Dead Bear Vibrations Tapestry. Artwork by Mackerel Graphics. Dancing bears swirling in an ethno-psychedelic wonderland. 3-D Tapestry – Artwork appears to float of the fabric when viewed through special Sunshine Joy 3D glasses (sold separately). The Grateful Dead are one of the most powerful bands of all time. They meant so much, to so many people, in so many ways. Millions of fans would put their lives on hold and tour with them for weeks (some years), and an enduring “Deadhead” culture was born. The still-thriving Deadhead community is alive and well today. Comes with a pair of 3D glasses.
