Hi Obergefreiter,
I can't tell anything about the originality, it is not my cup of te and the pics aren't really good: too small and bit blurry.
I am collecting for 15 years now and I have only come across one of these, although I must admit that I am not actively looking for these, but nevertheless: they aren't common. When I should come across one and the price is around 40 - 50 euros: I would buy it.
It is a little bit typical that he has three of these.
Good luck,
Poulton
