NYC has had me browsing around old deco websites and I randomly found this advertising collection of works put together by Gatochy.  The works are categorized by decade from the 1850’s-1980’s.  Also a cinema collection of posters. Pretty sweet resource.

Textures on flickr. They look unique! Nice patterns from different public transportation systems. View Ludwig’s Flickr Set here! I found another public contriubtion flickr set here that also has patterns of this nature.

Check out this site. Some really nice ‘old’ world wall paper textures.
