Logos 01 is an "essential primer" by designers for designers with blow-by-blow accounts of the logo design process. Since it showed up on my desk, it's been catching the eye of designers in the office and prompting them to say things like "I love books like this!"
Compiled by Minneapolis-based firm Capsule, the book uses six case studies and a logo gallery (both featuring Capsule's and other's work), it gives plenty of examples for dissection, as well as a guide detailing the steps from strategy and research to launch.
The first in a "Design Matters" series aimed at ambitious designers, the book has an easy-to-understand tone and features an accessible layout (naturally), making it a useful volume even for those who are just design-curious.
