The bottom board is one of my first production prototype four foot skateboard, which I test rode as one of my personal boards in 1972/73. The four-foot skateboards I had made in the mid 60′s were actually rectangular! The top board is one of the first production boards I was building myself to sell to the surf shops. The wheel wells are likely the very first wheel wells ever. The sand and resin textured top was the first skateboards with grip – which was the precursor to grip tape.” Boards courtesy Tom Sims.
