Since it is a stone litho work, then I also know it pretty well (the look, texture and feel), as I have a number from the '20s and '30s that were done in this way.
Stone litho work and its subtle way of creating shading and texture can truly be a sight to behold.
Really great, there, John. And I like that even in the mid 1950's, Egypt was still utilizing this technique, when offset printing had so much become more the standard printing method elsewhere, by then.
