All-Pro Skateboard
The All-Pro Skateboard trading card set was released by Donruss in 1978. It is comprised of 44 die-cut sticker-cards; 42 are regular numbered cards and the remaining 2 feature the logo for the International Skateboard Association on the front and have different backs.
Card fronts for this series depict a cartoon of either a particular skateboarding trick, displayed in a fantastic way, or a skateboarding character of some sort. Card backs show either a profiler of a prominent skateboarder (38 total), 3 cards telling the 'basic rules' of skatboarding, or a membership signup form for the afore-mentioned ISA.
Note: Donruss had produced a rather small and plain Skateboarding sticker set the previous year; they were very similar to the cardfronts from this series, and some stickers from the previous set have reportedly been found in All-Pro packs.
