If you are interested in taxes and tax stamps on playing-cards,
you can find here a compilation of stamps, information and information
sources sorted by country:
Playing-card taxes world-wide.
One of my main areas of interest are taxes and tax stamps in the
Electorate and the Kingdom of Hannover. In 1994, I published a first article on that subject.
In the meantime, I have gained a lot more information, and all of it is published in my book
Spielkarten in Hannover. A short summary of my present knowledge
about tax stamps in Hannover can be found on the page:
Playing-card tax stamps from Hannover.
