SEPARATION OF STAMPS: Comb perforation
Comb perforation is when the perforation pins have been arranged in a comb pattern to perforate three sides of a stamp in one stroke. You can recognize a comb perforated stamp by the fact, that the corner teeth look alike. Today’s stamp shows a block of four from Iceland (1931) depicting King Christian X of Denmark. It is overprinted “Zeppelin 1931” to celebrate the visit of the airship “Graf Zeppelin” in 1931. The stamps are comb perforated 14:14½. Please note the regular teeth in the corners of the stamps.
