Hi,
Just adding to floortrader overprint forgery. Yes it is and known on Nr.1 (3 Pf) and Nr.5 (50 Pf) loose stamps and covers.
Since my specialized book is overdue for a new edition, here is a Nr.2.
These were issued in 1908 and you can see the same overprint applied to a Nr.61x dated from 15 January1894. (For a so low valued stamp??)
