The pink 1.50 Franc (MiNr. 44) Pétain forgery is a bit of an oddity. Only two perforated sheets (80 stamps total) are known to have been produced, and L.N. & M. Williams, in their definitive work Forged Stamps of Two World Wars, indicated these two sheets were perforated 14 x 13.5, and the distinguishing feature is a lack of space within the value text (as with the MiNr. 45). This is echoed by SGM Herbert Friedman (Ret.) in his seminal work, Propaganda and Espionage Philately.
However, this copy is different. It has the other distinguishing marks of a forgery within the design of the stamp (as with MiNr. 45 & 46), but does not have solid value text, and has 14.5 x 14 perforation. It is signed by Mayer as a genuine forgery.
