Producing the pictures gave work to many graphic artists and lithographers. Tilgmann in particular specialized in producing these kinds of pictures between 1900 and 1930. Tilgmann’s printing house used both chemographic lithography and heliogravure printing, which made it possible to print large pictures and make copies of works of art. The pictures were designed by scholars of the highest level, who made sure that the facts in the pictures were correct, and artists were chosen to draw the pictures. In this way the pictures were of high quality in both content and appearance. The artists would paint and draw the pictures on stone slabs for the final printing.

The quality of these pictures was so high that some of them were sold to other Nordic countries, to Estonia, Central and Western Europe and even to the United States.
