Czech Hradčany stamps - Introduction 0.1

In the early days of newly created country Czechoslovakia, in 1918, a set of 26 stamps were issued between 1918 and 1920.
All over this issue, 5 designs were used : 

Design 1 and 2 are very similar:
for the lower values, 3, 5, 10, 20, 25, 30 and 40 haller, the texts 'POSTA' and 'CESKO - SLOVENSKA' are white on a coloured background (design 1).

design 1

In the higher values (100, 200 and 400 haller), the texts become coloured, and the background is white.

design 2

In 1919 a renewed design was made.
The word 'Cesko-Slovenska' is now horizontally placed. (design 3) - 1 and 50 haller

design 3

Later that year, a design error was corrected: the sun does not rise in the position behind the castle, and was therfore removed. All other items remained the same. (design 4) - 60, 80, 300 and 1000 haller.

design 4

Finally, from August 1919 on, a fifth design was used. The bush in the front of the design was removed and replaced by a full design of the Saint Nicholas church (design 5).
This design was used for 5, 10, 15, 20, 25, 30, 50, 75, 120 and 500 haller.
