The 60 Minutes segment that featured it had a portion that was devoted to the prevalence of trading to complete albums, and that these stickers were actually used as stickers and adhered into the albums. It is like a throwback to a few decades ago, and it was fun to watch the enthusiasm of kids and adults alike pursuing them for the joy of collecting.
