The following are my FAVORITE 1920, '30s, and '40s ties from my collection.
The crepe silk tie below is from the tail end of the 1920s. It's an extraordinary example of a distinctly '20s Deco design, as opposed to the later Streamline Moderne. I wear this tie with a cream linen suit and a cream shantung silk suit.
The '20s tie below was made by Sulka. This is the fabric that Sulka was famous for: a luxurious combination of satin and watered silk. I've been told that this fabric is no longer made: it was just too complex and expensive to continue being produced. The color is a deep purple. It's a stiff silk that makes a rustling sound when one ties it. (I should mention that in the later '20s, Sulka ties were wider than was the prevailing fashion.)
The early 1930s silk tie below was also made by Sulka. I'm just blown away by the "pop art" pattern, nearly 3 decades ahead of its time. You can put yourself into a trance trying to identify the faces: I'd swear that one of them (at the bottom right, just above the tip) looks like a bespectacled Bert Wheeler, from the early '30s comedy team of "Wheeler and Woolsey" (who kept RKO afloat in those years). I can't seem to wear this tie with anything ... but who cares!
This '30s silk tie below is from Cheney Cravat's "Game Birds" series: it's supposed to represent pheasants, and has an almost Japanese feel to it. It has the magical ability of matching practically every suit color known to humans. The only color it doesn't seem to go with is brown. I love this tie!
Below is the strangest 1940s tie I've got. All silk. From the very late '40s, it's what I call a "jazzbo" or "bebop" tie: I just can't imagine anyone but a jazz musician wearing it! Take a look at the knotless "knot".
