It's Friday! Whatzit time! You know the drill: I show you a picture, you guess what the object is/is for. This time, I confess, I am cheating a little. This is not an object from our permanent collection; this is an object I came across while cleaning my office. I'll post about something related next week.
On to the photos!
It's made of teak. The top rolls back. And there are little pads on the bottom.
So.... What is it?
