What I do know is the models used in this promotion, which I'm dating to 1939, were a rather stern group of women. (Definitely in contrast to the romantic photos on patterns during the 1940s).
This is the Sun Ray Collar No 16 with interesting rounded points.
This pattern was named only No 22. It's a very flower petal type affair (at least in my thinking).
Another pattern with only a number ... No 52. The design could be construed as honeycomb, or perhaps cobweb.
Okay, I've shared these photos ... can get back to work now !
Thanks for dropping by,
