I've been looking into Spain recently and by chance came across the matasellos turisticos.
We may all receive mail from Spain from time to time or send a card from there, when we are on vacation. Dropped in the post box, this might result in a disappointing cancellation.
This doesn't necessarily need to happen, as in fact there is a wide network of local pictural special postmarks available.
I wanted to know more about this and did some research. I found information on this on two websites
a) that of the post office - but only the stamps from the last three years are shown there
b) that of a private initiative, which shows all special postmarks since 2014, including a map view
The addresses of the post offices are listed as well.
In my opinion, an excellent and unusually rich offer.
A small sample

I am very impressed.
Viva Espana!
