 The righ hand two stamps appear to be inverted but I am unable to find any matching error on this stamp from Google search. The stamp printed April 4, 1925 Scott # 551. Flat Plate Printing. Hoping to receive comments on this post. |

Not inverted, just a gag stamp/cover. They were made by slicing out the portrait in the oval, and either gluing it on another stamp (in which case you can feel a rise in the paper with your fingernail, or by actually replacing the oval inverted after affixing the cut-out oval stamps on the cover.
If you enlarge your pic, or examine your cover, you can see the cuts in the ovals of the right 2 stamps (i.e., the ovals aren't smoothly rounded.
Whatever you do, don't soak the stamp off cover, the gag stamp will be ruined.
An invert cannot exist for this series because the entire stamp was printed with a single plate. Inverts can only happen when stamps are printed from more than one plate, in which case the paper was removed for examining and then put back in wrong direction for printing from the next plate.
