Original superb and rare Norton Motor Cycle double sided enamel sign.
An incredibly highly sought after example  with only ever two others coming to the open market that is known of.
It maybe that very few of these enamels were ever produced for the Norton Motor Cycle company which would explain why they are highly desirable to the collector.
The colourway of the yellow, midnight blue and white makes a great combination and very eye catching with a superb heavy gloss.
