I found this a long time ago, but...
One time, when we had a book fair at our school, it was what you'd normally do, buy books. But at the check-out table, they were giving away SMA2 Bookmarks! The neat thing about them was that if you got all 3 (which I do), you can link the together and they make the complete SMW overworld map if you put them in the right order! There was Mario, Luigi, and Yoshi. I'll try to get scans of them
An extremly rare and valuable Yoshi!
"Who want''''s to buy a gold Yoshi? Selling Price, $99,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999,999!" (almost 10 Googols!)
