A nice collection of photographs showing each page of the Barbican Identity Guidelines. Flickr set put together by Alastair Jones. Reminds me I need to get my ass into gear and take photos of several vintage logo books that I have. Just takes so long. :(
Another Flickr set of logos, this time: 1960's and 1970's Scandinavian Design Logos (Denmark, Sweden, Finland, Norway), from Oliver Tomas, covering : furniture, textiles, glass, porcelain, housewares.
