One of the most famous advertising characters in the world is Bibendum, the Michelin Man, who has been the advertising mascot of Michelin tyres for over 100 years. His image is iconic but has changed somewhat over the years.
He has always been made up of white Michelin bicycle tyres, but here he has pince-nez glasses on (that resemble the shape of a bicycle), and smokes a cigar.
Here his head has become a little more humanised. (He’s still smoking that cigar though)
In this poster from 1925 he is starting to more closely resemble the Michelin Man of today.
Here’s a more modern poster, from the 60s or 70s. Note that Bibendum’s eyes are made up of bicycle tyres.
