There was mail from an Ebay seller in Tasmania, Australia, in my mailbox today— with a single pair of South African stamps inside.

Notes:
The bilby (Macrotis lagotis) is a desert-dwelling marsupial about the size of a rabbit. It was once widely distributed through arid and semi-arid Australia, but wild populations are now restricted to spinifex grassland in Western Australia and the Northern Territory, and to a small region of southwestern Queensland.
