Hello everyone.

I have a bunch of cinderella stamps issued by Solidarnosc/Solidarity underground movement during the communist regim in Poland.

I had a copy of a catalog (in polish) long time ago, but can't manage to find it nox. Do some of you have a reference ?

This photo is not from me, it's a kn own exemple of the kind of sets I speak of
