Yellow Submarine bicycle seat by Permaco, measuring 8.5 x 9. In very good condition, with separations and surface loss at top corners, light overall soiling, and scattered light rusting to metal parts underneath. One of the rarest of all Yellow Submarine licensed merchandise, the bicycle seats were installed on the ultra-rare Huffy girl’s bicycle in 1968. Incidentally, there were more than 25 different licensees of Yellow Submarine products. RRAuction COA.
