Well, maybe only a cinderella lover would consider these stickers collectible. But I'm proud of these. I'm one of those people with a life-long, pathological fear of needles. Yet I allowed a friend to badger me into giving blood. Hey, it wasn't bad at all! And now I've given four gallons: that's 32 stickers, and I kept 'em all! Much credit is due to the great folks at the Central Florida Blood Bank on Gore Street in Orlando, Florida; they treat their donors right.
