Bass Ale has used the red triangle logo since 1876, when the logo became the first registered trademark ever issued by the British government (TM No. UK00000000001). Its simple design may have helped Bass become one of England’s leading beer producers by 1890. The logo became so popular that Edouard Manet featured it in his 1882 work “A Bar at the Folies Bergere” and James Joyce explicitly mentioned it in his novel “Ulysses”. Bass Ale is even mentioned in connection with the sinking of the Titanic, as it was carrying 12,000 bottles of Bass in its hold when it sank. According to Anheuser-Busch-InBev, Bass ale was even fought over by Napoleon.

It is still one of the oldest trademarks and active today!
