I would like to introduce another timeless classic: 

“Trademarks & Symbols of the World” by Japanese designer Yasaburo Kuwayama. 

This book features an extensive collection of logos and symbols from the mid-century era, particularly from Japan. 

It’s only available second-hand and tends to be expensive, there is a digital copy available. (I’ll link it below)

This book is highly recommended for anyone looking for logo design inspiration.

There is also a second volume of Yasaburo Kuwayama’s “Trademarks & Symbols of the World”
