The graffiti piece on Camden Lock Railway Bridge is considered to be the oldest surviving pieces of street art in Camden, having been created by John Bulley in 1989. Whilst working on a number of new shop signs in the area, Bulley was asked if he could come up with an idea for the Camden Lock Railway Bridge as it was about to be refurbished and repainted by British Rail. Knowing that he wanted the design to be visible from a distance and have some humour in it, Bulley used a bold typeface and photographed two men he was working with to include in his design. The resulting work features the two men who appear to be constantly painting the bridge.  The work has been repainted in recent years to freshen up the paint but using the same iconic design. Having lasted for over thirty years, the piece is considered an icon of London’s oldest pieces of street art.
