Those are not EURO bills, though they look almost like them. Those are prints of new social ad from Ukraine. If you look carefully on those bills you can see small depictions of young ladies standing near the buildings. There is a big problem of young women moving from Ukraine to Europe for better life but working as prostitutes there. These ladies on the pictures symbolize those girls, and there are also small the words like "This is how much you can get leaving abroad illegally" pointing to the nominal cost of the 5,10 or 50 EURO bills.
