Mi 12
Forgery |
|
The first Viking ship issues (Mi #12-13) were printed on two different paper types. The 1st issue in 1919 (Type x) was printed on white compact paper, while the 2nd issue in 1920 (Type y) was printed on coarse grey paper. All known forgeries of these issues by Jaan Lubi are printed on a grey paper type similar to the 2nd issue [1]. The most important design characteristics to distinguish originals from forgeries are:
There are also a number of other differences in design details, e.g. in the frame around the values.
