A transparent mailbox. With a clear plastic box, you could see if the mail had been delivered. The box wouldn’t rust or require painting – probably would need a regular clean though!
Rick Megenity, Seattle.
August 1959
I found this transparent mailbox on Amazon, although at the time of writing there were no sellers available.
