What are these "limits" of which you speak? Is that another Arabic term unknown to us non-Arabic speakers?
My "Collection Direction" is generally encyclopedic in nature. I collect for representation of form; with rare exception, once I have an example or two representative of a people, time, or culture, I stop looking. Hence, my "focus" really knows no geographic or ethnographic boundary, as I see my nascent collection as a tangible record of mankind's collective journey, through which I can occasionally plug into the gestalt of the human experience.
