I have a ton of these, from the early 70s to the late 80s. This set is what started my collection though. This one in from the early 80s and was the first set I ever got. It was also the first to have an official sticker album (although the stickers were much smaller than previous years).
In a way they are time capsules. They show what the original products looked like at the time, even if the cards were changed a little to be humorous. They also include many products that have been long since discontinued. The Whale-Os in the corner of this photo demonstrate that fact. They are a play on Waffelos, which was a cereal from the time these cards came out. Now worries, I am going to submit the original box of Waffelos too so you know what I’m talking about.
