The issue of the Austrian Newspaperstamp from 1890, 25 kr, rosa is one of the smalest of Austrian Stamps. Only 12,500 were issued!!! The Stamps are on special paper printed.
Stempel are extremly rare.
I can not find the two enclosed Postmarks in Mueller or Klein Katalogs. Only Anton Glaube, Band II, Page 24 shows a picture # 13 of one. Glaube's book was printed only in an issue of 300 Books, again rare !!
Please can you help me to find the Postmarks !!
