Flickr gallery of 70's logo designs →[More:]As a graphic designer, I learned my trade throughout the 70's, and my design sensibilities still lean heavily on what I learned back then. This is a nice set of scans from a book from the era, displaying logo designs. It really brings back great memories of design class.
Overall, I find these designs to be very strong and still stand up. Part of the challenge of logo design in that era was designing with a wide range of reproduction techniques in-mind. This includes making sure the design stands-up when reproduced in a one-color print. That requirement is what makes these older designs so strong. Today, a lot of designers never think beyond the web, so you get a lot of illustrative logos that don't translate to anything else beyond a full-blown 4-color print.
These sorts of books were commonplace throughout the 70's and most of he 80's, and were fantastic inspiration.
It's kind of...sad?...that the Flickr poster calls these "vintage". I guess I really
am getting old, eh?
