It is not a stamp. It is a propaganda label. The date in the bottom right corner shows "1935". I wonder if it has anything to do in reaction by Great Britain and the United States Jewish citizens to the Nuremburg Laws of 1935 that denied Jews in Germany the right to citizenship and was the first of what was to be additional laws that eventually denied the Jews the right to live.
Here's a link for more information about the laws:
Note the name "Roy Wemp" on the label. I googled "'Roy Lemp' Jewish" and came up with several hits. He was apparently a member of the British Israel Federation (Canada). Wikipedia has a short article on the federation, which was founded in 1919 and apparently still exists. Nice Judaica item.
The art very much evokes the teachings of the Worldwide Church of God, which based its' core beliefs on those of the British-Israel World Federation. At a very basic level they maintain the belief that the UK and the US are the descendants of the 10 lost tribes of Israel. They are a branch of Christianity, but are not Jewish.
Found this image online by the same organization:
They are interesting items for some conspiracy collectors.
David, If I had either of those cinderellas, I'd keep them in my collection.
The reason I entered Youpiao's 2 giveaways, was for a similar reason. Knights Templar related stamps/seals would make another fun conspiracy theme collection.
