Popular British tea company Twinnings is known to have the oldest logo that still exists without alteration. The logo design was created over two centuries ago, in 1787. The base of the logo is directly associated with the Twinning family crest, and a few references from China (the source of the tea) are also associated with it. Its simplicity and timeless nature require no alteration of any sort. Thus, the brand has the same logo to date.
