Life / Identity Card found in Poland. How to get it returned to the owner? [11]

Merged: FOUND: Travel Card 'Karta Miejska' in Poland - where to return?

Long shot....but I found a travel card in Sadyba this morning. I checked its validity and I think the owner will want it back.

It belongs to Maria Sobkowiak. If anyone on this forum knows her please ask her to contact me for its safe return.

Failing that, what is the proper thing to do? Return it to a ticket office? Where?!

Let's hope this works.
