How great is his moustache? I have a lot of menswear patterns to scan, but this is the only pre-70s one with a tache. The size of the pages are pretty large, so I’m confident this is from the pre-WW2 days when paper was scarce and patterns shrank.
At the bottom of the middle two pages is a great diagram for how to do a stretchy thumb cast on. It’s worth scrolling down to the last page which advertises other patterns which were available. It breaks my heart that I don’t own all of them.
