Out of interest I put a framed photo of the Vietnam wall in my wife's antique stall (she sells antiques as a hobby). I put that there in September. It sold last week. My best guess is people wanted it as decor for July 4th. Obviously I should put something relevant to public holidays in that booth. I don't regard the booth as a great seller - just somewhere I can publicise my work and maybe sell the odd print or two.
