I love the old fashioned look this poster holds. Fact is, it is old as it says '1903' at the bottom. The poster I found on a blog and the only names that were on there were " John Wilkins in The Baroque Cycle, Neal Stephenson". I can't work out what the poster is apart from its some kind of map for Washington DC? It seems much to technical for a letter press, but it could be a screen print; I can't be sure. The layout works well to. Usually when you use to many fonts on one poster you lose style and meaning. I think because this poster is black and white the poster works. I love the type face used on "Sanborn Map Company" too. All in all its a fantastic poster. I would like to explore typography similar to whats been used here.
