Door Knocker

Not just any knocker but the knocker from Alexander McCall Smith's "44 Scotland Street". To be more exact,the knocker on artist and illustrator Iain McIntosh's door, which he used as the basis for his design in the series. Needless to say it isn't in Scotland Street and not at any 44 either.
