This pin is a beautiful piece of a vintage collection. These were produced in the early 2000s and friends of the grateful dead will remember these pins having a strong presence at many shows for being carefully crafted with strong attention to detail. Each is stamped on the back with either signature, individual number, etc. Long since out of print from a very limited run. A tough to find pin for sure, especially in its condition, which is near mint. Happy to answer any questions you may have. You can check Twisted-Creations.com for my many other listings. Thanks for sharing the love of The Dead and Stewie!!!
