It’s simply an oil drip pan, bought from Walmart for $12. Cheap!
The oil pan had a grease coating on it which came off with SimpleGreen. I didn’t want to put (or try to put a hole in it for hanging) a hole in it so I use the 3M picture hanging velcro.

Yay! I had one of these in my first-grade classroom for my students to check in, choose their lunch options, and that sort of thing. I remember when I went back to the auto department to get it the clerk said, “You must be a teacher!” 🙂
