I received one of these as a gift from my cousin one year. It was the Donkey Kong one and I used it to decorate one of my book covers. Needless to say, I had the coolest book cover in the whole school. Well at least I thought so, but the majority of my schoolmates were strangely silent on the subject. I tried to get more of them, trolling the local Five & Ten weekly hoping they would show up there. Sadly the DK textbook was a one of a kind masterpiece. It is long gone now, but the memory lives on!
