Calling all Poles!
This postmark seems to read Korolˇwka k. Borszczˇwa.
This is the name of two different towns, the second of which is today in Ukraine.
Is this a TPO postmark? Both towns appear to be very small - especially the first - so I find it hard to imagine that there was once a railway line connecting them.
Also, what is "k." short for?
Any help would be greatly appreciated!
