i hope i dont violate against the rules

I would like to know what the experts here think about this flag. Orginal or not.

Last question would be how much is it worth? I do know that prices arent discussed here, i just would like to know the value of this flag. Eg. 800 to 1200 Euro or something. There is a production faiure on the right side, a round circle.

Size is 100 x 170 cm

Thanks everybody enlighten me.
