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. The earlier examples, those dating from the '70s, are generally the only pelons run on burlap. Few of these "tests" were preserved once the design was deemed acceptable and the shirt went into production.
