A very unusual piece of mid-century signage, this Shell 'Service for Motor Boats' enamel flange sign is dated to 1957 and remains in excellent, in fact near perfect, condition. 

 

The sign features a lovely, simplified graphic of a speed boat with the iconic Shell logo at the stern breaking through waves, the vibrant yellow, red and blue colours stand out nicely against the crisp, white enamel background. 

 

The sign measures 48.5cm wide x 42cm high and the flange is 5.5cm deep.
