Yugoslav Postal Tax Stamps

Yugoslavia was a predominant issuer of Postal Tax stamps during the past 75 years or so.
Postal Tax stamps were obligatory surtax stamps that were required during a certain period (for these Yugoslav issues, it was a week long period, usually between late Sept. and early Nov.) The additional "tax" was used to generate funds for various charitable organizations (for these Yugoslav issues, the funding was originally for the International Red Cross, and later, an additional issue was created for various Child Welfare programs).
Not only did Yugoslavia issue the Postal Tax (listed in SCOTT as RA issues) stamps, they also issued Postal Tax Due (listed in SCOTT as RAJ issues) stamps, for mail that was posted during the obligatory week which did not have the surtax stamps already attached.
I have almost all issues of these stamps, and hope to eventually get them all scanned, and uploaded into a gallery for viewing. For now, I offer a scan of the first issue, from 1933, including both the Postal Tax and Postal Tax Due issue. (the Postal Tax Due issues can be distinguished by the addition of the word "Porto")

Those are very interesting!
I never realized that contributions to the Red Cross were made mandatory using stamps like this.
Thanks for sharing them.
Do you have any on cover?

A few more scans I did this morning, just to keep this going.

Hello Kuhli,
I just wanted to send you some info about a stamp:
http://yugostamps.com/YU_TAX-homes.SHTML
unknown (1938???).
I assume you speak serbian? The documents are written in serbian - cyrillic. I found them in the Archive of Vojvodina and took pictures.
If you have a problem understanding, I can translate it to you.
Regards, Ildi
