This is where fakers like to work. CS Knives are my area of expertise, a place where fakes outnumber authentic 100:1. One mindset amongst fakers is to concoct fantasy pieces which nobody has seen--and thus no expert can question by previous experience. They simply are the "first ones to turn up." Regardless of the genre, I'm wary of the "only" or "first" anything, esp. if it's way-out-there.
Fakers also stick with what works and distract with false provenance, IMO, exemplified here where not only do you have the same flag, but the same type, size and date of a provenance tag.
Of course, there are plenty of fakes of all the known factory and established local patterns, regardless of the genre--but these are easily refuted by experts in the field.
