Vintage 1930's Crochet Collar Patterns in Tower Brand Gimp

A vintage 1930's leaflet from Tower Brand Yarn Corp came up in my stack for processing last that I just must share with you.   Now, I don't know anything about Tower Brand Yarn Corp.   I did quite a few Google searches, and all that definitely comes up is a list of their pattern publications.  On some of the searches I performed, Lion Brand Yarn came up, however, within those pages, I don't find references to Towers Brands, and so, I moved on.

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. 

All three detachable collars are on the larger side ... as was the 1930's style to bring adornment to the rather plain dress of the average woman.    All three of the patterns call for Tower Brand Gimp, which was a 50/50 cotton and rayon blend.  Many patterns with Gimp variations arose during this time period due to the Mercerized Crochet Cotton shortage during WWII.  Gimp was a rather stiff thread.   For current Gimp substitute, I've read that the DMC Cebelia No 10 thread works well.

Okay, I've shared these photos ...  I can get back to work now !
