It seems clear that the people who made these did get most, if not all, of the images they started with online.
And yes, we have no clue how these were created or used. Several have tape stains on the back indicating they were displayed somewhere, but where and under what circumstances remains a mystery. Perhaps an Egyptian version of "Alamo Drafthouse", likely unlicensed?
I have been mystified by many of the prices. Time usually brings such aberrations back into line.
Not one person has emailed us with any additional information about any of these.
