Tomorrow, i have to do a little presentation about a identity project based on photography. Here is a project by Gavillet & Rust, and i can't find the name of the typeface the used. I was thinking about the "Plain", a typeface they designed and available throught the Optimo type foundry. I'm not sure about the "Plain", and i would appreciate the help of someone. :) I hope my question will find an answer. All the best
