Those of us who were children in the late 1970s remember a form of schoolyard wampum that was ubiquitous at the time. We traded them with each other, and bought them from the corner sweet shop with our allowance, for 25 cents a pack. We’d huddle and inspect each other’s collections, muttering “got it, got it, need it, got it, need it.” We carefully stored them in plastic sleeves for the future, in meticulous fashion.
Haha! I was totally kidding about that last one. We stuck them all over our bedroom door, until our parents grew furious and made us scrape them off with a putty knife, turning them into garbage.
