About long-gone stationery: Years ago I owned sealing wax and a seal. It had a rose on it. I don't know where they went;I don't have them any more. But they were fun to play with while they lasted.

Remember how people sometimes put their return address on the back of the envelope? Word from the post office is not to do that anymore, because if the envelope goes into the scanner upside-down, the system will take the return address for the recipient's address and shoot your letter right back to you.
