I recently listed this Palm Beach tie:

along with some other neckties. I always thought of these as 1930s ties, probably because of the simple Art Deco patterns, matte finish, the lack of tipping - even the colors. But hey, look, I was wrong!

This came out of a magazine, of course, so we know exactly when it's from. And there's my tie, second from the left! I used to have one like the green one at right, too, which wouldn't look wrong with a prewar suit. And in the center, several patterns completely typical of the period. But some Palm Beach ties do date to the 30s:

That green pocket square would match the green tie of 1950 perfectly, and those striped ones seem to have been a mainstay for the company. Note the difference in the tags, though - in the postwar ties, the Beau Brummell tag has been eliminated, and the Palm Beach tag has been redesigned.
