In October 2018 Ebay seller 21veronika2012 from Odessa in Ukraine was trying to sell these completely fake plates.
The blanks are supposed to be Lithuania but they have the euroband wrong and the registration is not a Lithuanian one. It looks more like a Polish registration.
You MUST check everything carefully or you will end up with shiny scrap in your collection. If you join the big European plate society (Europlate) you will have access to all the information you need to understand if a plate is genuine. Between that and e.g. the Francoplaque website you should be OK.
