“Contrary to public opinion, the letterforms now typically associated with Le Corbusier were not designed by the famous architect himself. The common name for this lettering style, in France, is ‘Charette’, as this type of lettering was often used on pushcarts (called ‘charette’ in french), packaging, signposts, etc. — in fact, anything that needed labelling.
It is common knowledge that Le Corbusier often adopted everyday objects from his immediate environment for his artistic and architectural work. Typical in this way is the use of this common stencil set for titling his plans. Later, with Le Corbusier rising to world fame as one of the most important architects of the 20th century, this lettering style became synonymous with Le Corbusier, and Letraset even wrongly listed him as designer of the font in their old catalogues.” [Lineto]
