The entire 1973 Trade Marks & Symbols book is online for free
Hmm, this is interesting. The entire 1973 Trade Marks and Symbols book has been photographed, page by page, and posted online for free viewing.
The book features 1500 trademarks from all around the world organized in alphabetical order. So if you need some design inspiration or just want to look at lovely '70s (and earlier) design motifs, here you go!
