I got two of the old rainbow ones with my 6500 (one of them os on the back window of my car) and one of the big sheets of four with my Apple IIc+

Getting that old sticker sheet was almost as good as getting the computer itself

Ooo, LCGuy's post below reminded me that I also have the two big white ones from my MacBook, as well as eight of the little white ones from iPod nanos (two for my mom and I, and two from friends that didn't want them)
