If you haven’t heard already, I’ve been raving about this book. It’s called “Elegant Lettering From Design’s Golden Age: Scripts” by Steven Heller and Louise Fili. This book has high resolution scans of print ads and packaging from 1900 to the 40s. This is a very inspirational book and a must have on your shelf.
