AUSTRIA, Definitive Stamp Issue 1850/54, 3 Kreuzer dull pink, machine-made paper, Type IIIb *(*)
Old Austria Special Catalog 2008, No. 3M IIIb *(*) / €600.- ++
In my opinion, this item (see color image) is genuine and has been marked with my signature.
The stamp has original gum verified under a quartz lamp, with tiny traces of hinge marks in the hinge area. It displays several natural horizontal gum creases, which are production-related and barely noticeable.
The stamp is narrowly full-margined at the top, widely margined at the bottom, and has surplus margins on the left and right.
This is an unaltered, fresh (almost mint) MAGNIFICENT SPECIMEN!
