I love this book. I'm so glad it's available through Daisy. Although the Archive should really make the plain PDF version available.
If you can't find it elsewhere, use the 150 dpi PDF scan I made of the original 1934 book, which I own. It's on my website. It's 18 MB.
Or if you want a completely typeset , new 300 dpi, high resolution pdf version, with full color photos of artwork in the back section, and footnotes, download the 400MB PDF version I made for myself.
These PDFs are free at www.PaintingAPortraitByDe

The latter site has reference pictures as well.
This book went out of copyright in 1934 in the UK. It was never in copyright in the US after 1961. It was never renewed.
