This Adam dates from the mid to late 1950s. It has a porkpie crease without the center bump-up. The ribbon is tri-tone, with a back bow. Adams of this era used a plastic protective barrier between the sweatband and the felt of the hat, which shrinks up something fierce with age and heat. It’s easily remedied by simply ripping the plastic out of the hat. As you can see, this one had that problem.
This Brock porkpie is from the late 1950s. The size tag is very similar to what was going into Stetsons and Mallorys of the period. I wonder if this was made under license or if it was just a coincidence.
This hat is a mystery. I’ve seen them show up on ebay from time to time. They’re mostly all from this company, and all are from New Jersey. They’re all oddball colors. Masonic? Mummers? I would guess some kind of fraternal organization.
