A small request

Hello to everyone and happy new year. Apologies for using English Language. I would like to ask if there is a philatelist or a stamp collector that can help me.

On December 2nd Polish post offices issued a First Day cover under the theme Skarby Ziemi. This cover portrays a building related to Salt Mine of Bochnia, a city where my mother was born. I would like to ask if someone can offer this cover. I can offer two postcards written and posted from Cyprus or a set of Christmas 2021 stamps from Cyprus. Of course I could buy the cover online but having a swap is much better.

Hi @Prodromos :raised_hand:
I could check on Monday if this FDC is still available in the philatelic shop in my city - if not, I can see that there is still to get here: Poczta Polska Philatelic Shop - Envelopes / first day covers (poczta-polska.pl)

I bought this set a month ago, but I do not have the envelope.
