Mark @TheBigYin used to advise printing off your candidates, leave them lying around (or on a wall) for a few days and then choose. Seeing them printed means seeing them differently, more like others will, I think.
Well, that's this month's entry in; an opportunistic find whilst driving home the other Saturday afternoon. Shame the light wasn't a bit better, plus I only had a few seconds to grab the shot as the owner was just about to tow it away by the time I'd got back with my camera! He seemed a very nice chap though and delayed for a moment to let me take a photograph.
