India Tyre and Rubber Co, of Inchinnan, Scotland opened their factory on the site of a former aircraft manufacturers in 1927. Initially the Scottish tyre manufacturer was very prosperous; at their peak in the 1930s they employed over 2500 factory workers and had the architects of the Hoover Building design their offices - which are still regarded as one of Scotland's 'hidden wonders'. However the company only enjoyed around 50 years in business, vacating their factory in the early 1980s. 

This large enamel sign would've been produced during the company's more successful years, probably dating from the 1930s/early '40s, it features bright, strong colours and bold, outlined typography. Measuring in at 1.83m wide, I believe this is the largest variant of sign the company produced. India were relatively early adopters of 'paint on metal' advertising signs, which makes these nicer, enamel examples earlier and more unusual. 

The condition of this sign is 'reasonable', as you can see in the photos it hasn't lived the easiest of lives, but I feel that in this instance the wear and tear adds to the character of the piece without detracting from it's graphic appeal. There are numerous areas of enamel loss across the face of the sign and subsequent corrosion. Generally the corrosion to the main area of the sign hasn't worn through, though in areas on the outer edges it has. Due to it's size the sign won't sit flat until mounted on a wall - to ease the hanging of it, it has been mounted to a basic wooden frame with mirror plates attached. It could either be hung using this or removed from the frame and fixed directly to the wall. 

The sign is 183cm wide, 91cm high and with the wooden frame 2cm thick.
