Vintage Postcards - Boring! #2

Not all vintage postcards are of interesting locations or scenes. Find the most boring vintage postcard (pre-1980) you can find, and send it to your partner. The subject doesn't matter, just so it's desperately dull!

The card can be sent naked or in an envelope, and can be used or unused, but should be in good condition (nothing smoky/stinky, torn/damaged, mildewed/dirty). No reproduction cards.

The design is sender's choice, but try to send something you would like to receive and that you think your partners will like.

Optional: If you want, you can include a note explaining why you think this card is boring.
