the plate in the newer picture is a unofficial copy and is also illegal
In Ukraine, it seems to be normal to see foreign cars with unofficial copy plates. As far as I know it is popular for Ukrainians to register their cars somewhere in the European Union, but drive them at home in Ukraine.
As far as I know they drive cars which were registered to a previous owner so they make replacement fake license plates (in case the plate was stolen/taken by owner/other causes). They do it because duty and other expenses are high due to the fact that they are not in European Union. They also pay foreigners to register cars for them. In Poland, the record-holder registered almost 700 cars for Ukrainians.
