In 1913 a commemorative set was issued to celebrate the centenary of restored Dutch independence. It is quite a popular set of 12 recess-printed stamps with the portraits of King Willem I, II and III and Queen Wilhelmina.

The stamps were very popular at the time of issue too, for the design has been used for many advertising purposes. Like this one for the tea company Karel's Thee in Groningen.

This example here is a letterpress printed copy of the actual stamp (in larger format) with a fake cancellation, reading "KAREL'S THEE GRONINGEN". The whole set was reproduced in this way. They also produced a similar set with their company's name included in the design. I'll show you that some other day.
