Interesting find I discovered a few weeks ago.
I saw a Commonwealth Stanley Gibbons stamp collectors book in a charity shop. Its basically a British book publisher that’s considered an authority on the value of old stamps. This book dates from 1956.
This book just covers countries of the British Commonwealth only. I didn’t end up buying, just snapped a couple of photos;
This caught my eye. This stamp dates from 1918.
The one Piastre refers to a small value coin used by the Ottoman Empire, ie: the Turkish. In the 1920s these stamps were made obsolete by the British who took over.
Therefore these stamps showing “Occupied enemy territory” is not referring to Jewish people, its referring to Islam.
To avoid putting big files on my WordPress account, I’ve listed these on my Google drive cloud storage space to share if you would like a closer inspection. Apologies the 2nd page is a bit blurry.
