I’m not familiar enough with the work of the separate members. Do you have a sample of this specific version? Are there reasons specific to this version? Are there details about it that you really want?

You might look at HTF Didot or Ambroise from Typofonderie (site is currently on a break it seems.)

dont you mean this one? Didot Elder = Didot l’aine if im not mistaken.

Didot Elder is the first revival of the fonts published by Pierre Didot in his Specimen of 1819. Didot was the most important artistic director, publisher and typographer in France during the Neoclassical period.

Thanks Thierry, I’ve been looking for that one as well, it featured in Grafix magazine a while back and I had forgotten the name.
