Circus in America
I found this beautiful book at one the book sales from the Pimafriends. The vintage poster, lettering, and illustrations in this book are a great reference for color palettes, illustration styles and vintage lettering.
I still can't believe I purchased this book for 2 Dollars! The styles represented in the huge amount of images is a blast! If you need a book for reference this is really a good catch! Glad I found it!
