Rhe postal services got their own printing machines in 1933,
and the printing technology was changed from letterpress printing
to steel engraving. All the stamps were adjusted and became more
accurate.
The biggest change was made at the high-values with the kings
portrait, which was changed to the newest.
Special Stamps
The stamps made for missing payment of a letter were also changed
to be made by using the steel engraving in 1933.
