One of the biggest buyers of the Farouk Collections was Kasimir Bileski. Many of the cards displaying the stamps were put together by him as were certain backstamps authenticating them as coming from the Royal Collections.
In my time of purchasing Canadian rarities from him he would send me such items as gifts/incentives for purchases. Being specialized in Egyptian philatelics I recognized them and made a few large purchases from him of proofs and yes...what are called "crazy perfs".
I have since sold most at a handsome profit and many are prized by Egyptian specialists.
Many sets such as the one at the beginning of this topic are often actually rarities. Not saying the one pictured is
but I would make close inspection of them as they may be a color variance, perf variance, have a small error in design unseen without magnification, gum variance....on and on.
Many stamps the king collected were gifts from various leaders and diplomats of many different countries. Many are
The stamps sold for shall we say peanuts in 1954 as Egypt and such was not a very popular country collecting wise at the time. Many sell for 1,000's today.

Mr. Bileski was quite the investor in these type of sales. He was a major buyer in the sales of the Waterloo and ABN archives. His final investments were from the Format International Security Printers archive. His final purchase a whopping 300,000 GBP's worth!
He was one of the largest Canadian Stamp Dealers in Canada.
His true passion was the research. He once told me that he much more enjoyed the research and discovery of new and rare items rather than selling stamps. Profiting from the sale of them just came with the territory. Much of the Royal Collections were new discoveries in Egyptian Philatelics and elsewhere.
