Ride the Popularity Wave
When a plain old skateboard isn’t enough and you need to add a motorized sound to get the kids excited, the Irwin corporation has you covered. The advert is most likely from a 1965-66 Playthings Magazine, an industry publication for toy retailers. A suggested retail of $1.98 ( Under $17 according to the US Inflation Calculator) would have gotten you a noisy plastic sled that didn’t really turn. Fun! Time to “cash in on this surfboarding business.” Order your Whoom-m Jr. Sidewalk Surfer now!
