"Montserrat is a family of fonts designed by Julieta Ulanovsky - one half of design agency ZkySky. It was actually funded by a Kickstarter campaign and is distributed for free via Google Fonts."
"The old posters and signs in the traditional neighbourhood of Buenos Aires called Montserrat inspired me to design a typeface that rescues the beauty of urban typography from the first half of the twentieth century," says the designer. Pick it up in Regular, Alternates and Subrayada. See it in action at design blog Digital Abstracts.
