I have a 1960s Eckes post card when they were US made. It looks nothing like those. I also have the 1960 catalog when they were made by Adam, and it looks nothing like those. Wish I had more catalogs.
Eckes came to mind first for me and is still high on my list.
I call these "carnival cues". When I was a kid a carnical came to our area. You could win tickets playing games and buy prizes with tickets...you know the drill. The more tickets, the higher the prize was displayed. Up high on the wall was a cue and case. It had pearl rings, points, and a bunch of dot inlays. Sort of like a cue like this but even fancier. I always remember that cue when I see cues like this. It might have been the first two piece cue I ever saw. I was about 8 to 10 years old I think.
Obviously that's the first best guess, but I hate leaving it at that. Some of them are in fact US made, and some of them are Adam made. And then, some of them are just nostalgic.
There was a similar unknown that was relisted several times on eBay that I almost bought several times. It ultimately sold in June for $50.
I should have bought it. Why? I dunno. I'm crazy. But, I do have the pictures.

So, if I figure it out I will post it.
