I believe that the Bass beer trademark is the oldest, as it says on the bottle!
From Wikipedia: Bass is the name of a former brewery and the brand name for several English beers brewed in Burton upon Trent. Bass is most particularly associated with their pale ale. The distinctive Red Triangle logo for Bass Pale Ale was Britain's first registered trademark.
