'Agia Aikaterini

I was delighted to be able to add to my St Catherine memorabilia a few days ago with this Greek icon, allegedly from the 1950s, discovered on eBay. It is teeny-tiny, only about three inches in height, and in fact tinny - the cheapest imaginable form of devotional item, printed on rough paper and mounted on a chunk of pine, held in a desperately thin tin frame. The image of Catherine follows the traditional iconography but facially she does look rather like a long-forgotten B-list actress of the time. I'm not at all sure what the tower in the background signifies. On the back is a pencil scribble which seems to read 'Mazbe', though I have no idea what that might mean or even if it's right!
