Arthur Szyk - Stamp Designer

I have a signed card, illustrated below, showing 2 1950 Israeli stamps designed by the Polish Artist, Arthur Szyk. I have discovered that another set, Liberia, 1949, "Ashmun" was also designed by him (Vance Auctions has a signed card with this set as well). I also know that he designed anti-Nazi poster stamps at some point and have seen illustrations of them.

As an admirer of his more well known work, I wondered if anyone was aware of any other postage issues that he was involved in.

Two threads here come to mind...

Interesting Info. I was aware of his connection with Bileski. That's most likely where I picked up the card in the first place. And the charity labels and the Anzac one were new to me. It would be interesting though if he did have other "legitimate" postal designs - an easy collection to complete.

In terms of anatomy, that has to be the strangest looking pose, I have seen in a long time!

If not completely impossible, it would definitely need a visit to the chiropractor to sort out. And such a delicate, feminine looking neck to twist around on top of it all.

Nice example of his work though.
