French graphic artist Vahram Muratyan launched his Paris vs New York blog in the fall of 2010 and it quickly became an internet sensation, leading to a book in 2012. The clever simplicity of the illustrations and immediacy of the subject are the main attractions, but I think the project’s popularity is also due in large part to the signature typeface, Cabernet, Jason Walcott’s (somewhat imperfect) digital revival of the ebulliant and swashy Benguiat Caslon, released by Photo-Lettering in the 1970s.
One can access a more careful rendition of the original typeface at House Industries’ Photo-Lettering service, but I’m not sure all those crazy swashes are available there.
