I had stacks of them at my old campus job. STACKS!
Probably from the Apple Rep.
A company I worked for back around 1990, when PC's/Clone/Windows were only starting to become prevalent in business, was all Macs.
The Apple Rep gave me some *way cool* stuff. I decided to keep the Apple stuff I had gotten, and all of a sudden had a collection. Wow, now some of that stuff is worth a lot of money, especially stuff directly from Apple corporate.
My friend at the time was a teacher for a school district that was all Apple, and he got some pretty cool Apple Education stuff as well...
