I love Reddit and discovering this series of scans from The Ad-Man's Deskbook is one of the reasons why. There are nineteen total scans in the gallery and it's definitely worth clicking through to see the rest.
The book was uploaded by a redditor:
Recently my grandma passed away, and we have been going through everything she kept, which included a pretty large collection of my grandpa's old design books. His name was Sidney John Woods and he was the art director at Ealing Studios, an eminent film studio in England, between 1943 and 1959.
