Already notorious as a red light area, Chris Bracey transformed Soho in the 1970s using neon lighting.
He made signs for bars, clubs and tattoo studios and his work is now collected by the likes of Elton John, Jay Z and Kate Moss.
Some of his creations are about to go on show at a London gallery.
Chris Bracey works out of a studio called God's Own Junkyard in east London.
He often uses reclaimed old signs or other discarded objects.
Jay Z has commissioned three pieces, Sir Elton John had a sign for his son made and Ray Winston wanted a neon sign for home bar.
