This “shirt jumper” is from earlier in the 1930’s and was bound into a book at the British Museum. Unfortunately this gives a bit of a wobble to the page when scanning. Did you know that the scanners I use at the British Library upsidedown compared to a photo-copier? You lay the book on the scanner bed looking up at you, rather than face down and in this case it wouldn’t lie flat.

Lovely pattern, interesting with the offset rib. If I didn’t loathe ribbing so much, I’d make this. Still might, though 😀
Thank you so much for this bounty of 30s patterns you’ve been sharing lately. Some seriously amazing things. Now which one to knit first . . .
Thank you! I think I would change the pocket and collar on this one to single rib like the placket. Actually, I might omit the pocket altogether to show off that lovely staggered rib pattern.
