Hi there,

I'm looking for the exact font on the photo. All matches seem to differ in some way. Anybody got an idea?

Thanks!

Similar feeling

P22 Pop Art Stencil is close to your image and is a fairly smooth rendition of a bold Didot style.
No mention of source, but I suspect French stencils similar to those cited by the author of LL Liberte.
Pop Artists mentioned in the P22 description were eclectic in using everything from comic strips to soup cans as sources for their work.
UPDATE: Further checking persuades me that the artist is Le Corbusier. See following posts.

FF Flightcase would also seem to be derived from Didot style stencils. Rougher outlines than your image.

Le Corbusier is also based on the French Stencils
A version of Le Corbusier's stencils was marketed by Letraset as Charette.
See the James Mosley's history at:

Jeanneret NF is a crisp rendition by Nick Curtis of Le Corbusier's stencils
At a price of only US $ 10.00, it is my recommended choice of the various suggestions.

Manfred Klein's LeArchitect is a free version here at Dafont

Whow, thanks for the detailed suggestions! I think Le Corbusier is the best option for this particular purpose. Much appreciated.
