Here are a few examples of radio revenues. I collect these stamps from all over the world.
From left to right, with (J.Barefoot Benelux Revenues Catalogue) numbers:
1941: 75 cents, # 1 - issued under the German occupation,
1941: 75 cents, # 2 - on second thought, the Germans didn't like the two five-pointed stars,
1942: 1 guilder,# 3 - the annual license fee had changed to DFL 12,- ,
1954: 1 guilder,# 5 - remained in use until the last stamped radio licenses were issued in 1962.
Look here to see the source of inspiration for stamp #2
1942 Radio License
1961 Radio License for an extra radio receiver
Indonesia
1992 UK TV License (detail)
As soon as I have found the time to scan some more images, they will appear on this page.
If you have any information on radio and TV license revenues, please send me e-mail.
I started a mailing mailing list for anyone who is interested in this material:
