Despite the fact that the Amoco oil company is long since defunct, the World’s Largest Amoco Sign, built in the company’s heyday still towers over a Missouri intersection more as a copyright placeholder than a tribute to the company’s legacy.

The name Amoco used to be synonymous with gas stations all around America, having slowly built their huge company after becoming their own entity during a monopoly split in the early 1900’s. By the 1970’s the company name and its iconic central-torch logo could be seen in almost every city in the country. During the heady days of the company’s expansion, a massive logo sign was built on top of a St. Louis gas station that was actually wider than the building it was perched on top of. However by the late 1990’s Amoco merged with British Petroleum and the iconic American logo was swiftly replaced across the landscape with BP’s green pastel suns. However some stations still retain the original Amoco signs not so much out of nostalgia as evidence that BP still holds the copyright should they decide to revive the brand.

The massive sign that was when it was constructed and will continue to be for the forseeable future, the largest Amoco sign in the world, is one of these holdovers. However it now rests atop an expanded and heavily branded BP gas station, making its strange sign-out-of-time existence all the more stark.
