This collectible Jerry Garcia t-shirt was commissioned by Jerry Garcia Music Arts, a foundation inspired by the late great Jerry Garcia. The mission-based company believes, as JG did, that music and art bring great healing to the world. This t-shirt was created to help bring music to those who need it most - that's why 50% of the proceeds from this shirt will go to The Guitar Center Music Foundation, a non-profit that brings musical instruments and music therapy to those in need. Made by Bears for Humanity, this t-shirt is made from 100% organic cotton and was dyed using eco-friendly, water-soluble dyes. It's a gift and memorabilia item you can feel great about. Dyed with Water-Soluble Eco-Dyes GOTS Certified 100% Organic Cotton Certified by the World Fair Trade Organization
