J. Holler refers to several colour shades and 2 different perforations for some face values. Also the types of paper are hardly described.

Let's stick for a while to the 5p as it turns out to have at least 3 types of paper combined with 2 types of perforation:
Comb perforation 13.182: 13.529 29/23 teeth hor./vert.:
- orthogonal watermark, asymmetrical paper mesh, direction of paper runs parallel to the long side of the stamp:


- parallel watermark, asymmetrical paper mesh, direction of paper runs parallel to the long side of the stamp:


Comb perforation 13.666: 13.529 30/23 teeth hor./vert.:
- orthogonal watermark, asymmetrical paper mesh, direction of paper runs parallel to the long side of the stamp:


- parallel watermark, asymmetrical paper mesh, direction of paper runs parallel to the short side of the stamp:


All types of paper are imported!
