Question:
I have in my head that this is a lid to a Hall casserole; however, I cannot find it anywhere. Help!
Answer:
Here's one of the best Hall sites I've found...but I don't see that pattern. It looks like Hall to me too.

Answer:
Did you ever find out who made it/pattern name?
I looked through my Collector's Encyclopedia of American Dinnerware and didn't see you decal in it.
Funny, I'm having the same problem IDing a lid I picked up a couple of weeks ago that I thought might be Hall or Harker or ? I could have sworn I seen the pattern before but like you I can't find it. Arrrrggg.
Maybe we should make this thread the mystery lid thread. lol
Anyways, here's mine in case anyone recognizes the pattern/maker. Hope you don't mind me sharing your thread auctiongueen.
Answer:
Nope, never did find mine but admit that I haven't been looking hard. It will probably be next week before I can focus on it again. Figured I would go ahead and bump this thread up. That's about as much help as I can give.
Answer:
I forgot about Harker. There must be a decent site with their patterns as well...
Answer:
This is the only Harker ID site I have. I found some of their links are Page Not Found but the backstamps and the Harker Gallery at the bottom of the page works. They have a lot of named patterns.
Harker Pottery USA
Auctionqueen I'm 99% convinced your lid was made by Universal Potteries.
The evidence. lol
A Universal casserole. Blue stripe instead of red.
A Universal jug with your decal and they show the backstamp.
The only mention I could find of a 'name' for your decal is in the Offical Price Guide for Pottery & Porcelain by Harvey Duke. He called it Chrysanthemum for whatever that's worth.
I found mine also. It was made by Homer Laughlin and has the wonderful pattern name of KK350 according to Robbins Nest website, the only place I could find that decal.
