Spot the Difference if you Can #12

These Danzig stamps from the 1920’s are fairly common, but there are many varieties that can be found if you know what to look for. Many catalogs and reference materials refer to a French term, namely Burelage. This term refers to an intricate network of fine lines, dots or other patterns printed over or as the background of some postage or revenue stamps to prevent counterfeiting.
But many collectors are not aware of the pattern and most overlook it. These Burelage varieties can be quite valuable especially when postally used, in period.The two stamp shown here are Sc# 29 & 29a. But the varieties can be found in the whole series from Sc#25 to #30. There are some rarer varies with the Burelage doubled. Keep a close eye for those as they are even more collectable if you can find one.

Types of Burelage
The two major types of Burelage encountered in this series consists of Burelage Points UP  or Burelage Points Down.
The image on the left is Sc#29 and if you look closely, the Points are pointing UP, which is the most common one found.
The image on the right is Sc#29a, with the points of the Burelage pointing down. In essence, the Burelage is inverted, but historically they are referred to as UP or Down.
There is also a doubled Burelage variety and is easy to spot when you see it.
