It was so called due to the concentration of industry along this short stretch of road.
This section of the Great West Road was opened in 1925 in order to bypass the notoriously congested Brentford High Street and several factories of architectural merit were rapidly built along the road to take advantage of both the good communications it provided, and the easy availability of land for new buildings.
The sign was removed to Gunnersbury Park Museum in September 2004 after a brief campaign to preserve it in situ.
A replica was subsequently installed, then controversially removed at the end of 2015 and replaced with a digital billboard.
Another memorable animated signage was of a female diver advertising Jantzen swimwear.
