Pelons are extremely rare "practice pieces" for the early t-shirt designs. Before production was initiated, the image or design was tested on cotton cloth or burlap to determine the color and line accuracy of the piece. Only a few of the "tests" were preserved once the design was deemed acceptable and the t-shirt went into production.
New Year's Eve was one of Bill Graham's favorite holidays, and he spent much time and thought on its proper celebration. The Grateful Dead made another of their regular New Year's appearances for Graham at the Oakland Coliseum.
