I get a kick out of older lamps. The majority of lamps in my house are vintage. Among other things, I have a number of ceramic lamps with drip glazes, including one in a brown that reminds me a bit of my brownies.
Here is my combination BBQ timer & light for night cooking. If you put a nickel in it, you get 60 minutes of light. I actually keep it in the guest room, but I do keep some nickels near it. It also has a standard switch on the socket, so you can turn it off that way-but you still need a nickel to turn it on.
If memory serves, it is a Duncan parking meter & the company used to make these lamps from their old meters.
