Vintage Retro Shell X-100 Motor Oil Automotive Advertising Sign Collectible Rare

Rare advertising sign for Shell X-100 motor oil. I couldn't find another online, so haven't been able to date it, but my gut feeling is that it may be from the 1960s. Printed on aluminium, it's a great graphic with wear as per the images.

The distressed look may not please the purists, but it has a great look and dimensions that mean it will suit a variety of settings.
