Castrol Motor Oil Enamel Advertising Sign Wakefield Oil c1920

An original early 20th century enamel advertising sign for Castrol Motor Oil, produced for garage and workshop display. The sign features the classic Castrol colourway with bold black lettering on a white panel set within a yellow roundel on a red ground, advertising “Castrol Motor Oil.” This branding is associated with the British lubricants firm Wakefield Oil Company, whose Castrol products became synonymous with early motoring. The sign shows pronounced industrial wear, including enamel loss, resulting in a strikingly honest survivor with strong visual impact. Despite the losses, the core graphic remains immediately recognisable, making this a highly decorative and authentic piece of early motoring advertising.
