Royal Society of Arts Royal Presidential Medal (1965-06-15)TfL Corporate Archives

It wasn't always called a roundel!

Memo regarding renaming of the Bullseye (1972-03-17) by London Transport ExecutiveTfL Corporate Archives

The symbol was known as the "bullseye"

It wasn't until 1972 that the bullseye got its now more familiar name of the roundel

So where does the symbol come from?


The origins are obscure, but it seems to be developed from the symbol of our predecessor company, the London General Omnibus Company (LGOC). The LGOC adopted the design of a wheel with wings as a motif and registered it as a trade mark in 1905. The company name was arranged around the wheel and the word General appeared on a bar across the centre.
