Everyone in the department I work in is doing a little desk clearing. Consequently, a designated area (on top of the microwave in the common area, to be exact) has been created for unused stuff that everyone's finding in the back of their drawers. All items in this area are free for anyone to take. So, of course, I ran over as soon as I found out to see if there were any treasures left behind. Sure enough I found a few unique items that I don't think I will be able to find anywhere else.
The above mug is promoting one of our instruments. Notice the unique shape of the handle with the rotating dollar sign.
