Israel 6 Days War Cinderella

I'm looking for any details related to these Poster stamps.

Also, there is the abbreviation STS in the lower left corner - what it might be?

I have a large collection of Israel military mail but have not seen these stamps before.

I have sent the picture to a couple of my contacts to try to find out and if I get a response will post it here.

They may well be some type of propaganda stamp message.

Thanks Triangle.

I got this info from a local contact:

"Those are Cinderellas & not real stamps or proofs. After the Six Day War dealers here in Israel made tons of material for collectors because it was a very popular theme among the collectors. Old dealers told me it was possible to make a fortune on material of this kind"

This is along the lines of my original thoughts. They are not valid for postage! I am guessing that the STS is a dealers, artist or printers logo/initials.

I don't think this is a KKL/JNF item as these labels were produced for charitable purposes and have KKL on them. It could be the STS is trying to imitate KKL. I have checked several old catalogues and they are not listed. Several Israel dealers put their logos or initials on material especially things like maximum cards.

I will post again if I find anything else!

Thanks again Triangle.
