"A stunning set of Austrian Semi-postal stamps with perforation errors.
This series of stunningly high quality stamps are supposed to all be perforated at 14 by 13 1/2 (the catalogue album sheet is incorrect stating 14 1/2 by 13 1/2 perforations - the correct perforations are 14 by 13 1/2). However, several of the stamps in the series are amazing peroration errors. All the vertical perforations for the stamps in this series are a consistent 13 1/2 perforation. However, the horizontal perforations on several of the stamps vary from the correct 14 perforations. The #B210 for instance is an amazing 14 1/4 by 13 perforations. A 0.25 perforation difference is considered more than significant in philately. Even a 0.15 perforation difference is considered meaningful difference among stamp experts."
