In August 2017 Ebay seller jbeerd from Moscow in Russia was trying to sell these replica Swiss diplomatic, Senegal, Paraguay, Bolivia and very old Swiss postal plates. He says he has 5 copies of each.
As usual with his replicas, none of the plates is quite right.
The big problem is going to come later when some of these plates get into the market. From a photo during a sale or trade it could be difficult to tell if the plate or plates are genuine or not.
This just makes everything difficult for everyone. Reproductions are very bad for the hobby and if you care about the future of the hobby, it is better you do not buy reproductions, especially poor quality ones like this seller makes.
