Pattern Dating Help

Hi everyone!

I recently bought this pattern on its etsy:


It was a bargain for $5. The seller dated it at 1940s, but I am wondering if it is earlier? It kind of reminds me of some 1930s patterns I've seen. So, I'm appealing to you pattern dating experts - when do you think it is from?

Come and visit me at my blog if you've got a spare minute - I've broken my right (and dominant) wrist - the scaphoid - and I'm compensating for no sewing with some pattern collecting.
