pre-WW2 real vintage PC swap

Do you have some REALLY old, real vintage postcards from a thrift store or somewhere else, par example from the heritage of your ancestors that you are ready to share?

For this swap, you should send 1 postcard + note in an envie to your partner.
The card shall be made before the second World War [even better if it's pre-WWI], in the best condition possible. Please don't send trash to your partner.
It can be unused or used, but if used, the writing and postal marks shall be old and original.

Please attach a small note that tells something about the card. Some ideas:
- what's the story of the card? how old is it?
- how and why you had it?
- what changed, how does the scene that you see on the card look today?
- what is written on it? Any ideas who might have wrote it?
- etc...

You have 2 weeks to complete the swap.

[This time, only postcards, depending on the success of the swap, there might be swaps in the future that include other vintage materials, like photography]
