Letterheady is a archive site dedicated to (you guessed it) letterheads. Above are just a couple featured from the sites growing library (Top) 1941, the suitably modest letterhead of world-renowned bodybuilder Charles Atlas, ‘The World’s Most Perfectly Developed Man’ and creator of the Dynamic Tension exercise system. (Bottom) Early letterhead from the offices of legendary Manchester-based record label, Factory Records.
This is a good site and it leads to some interesting stuff further out there in the blogsphere.
