Here's the Jet Malt Liquor 16 oz flat from Westminster in Chicago. I also have the matching 12 oz flat and it has Continental Can Co's "triple C" logo, but the pint flat doesn't have a can-maker's logo anywhere on it that I can tell.

Back to a previous comment asking about the 16 oz Richbrau tab from Home Brewing Co. in Richmond, VA: That can came out as a last gasp right before they went out of business in 1969 and is extremely tough, even for collectors in the Richmond area. It took me years of looking 'til I finally got a rough faded example, and then a few more years later fellow Richmond collector Danny Morris let me get his can which is the one I still have now. After Home Brewing Co. closed operations in Richmond, Richbrau Beer was acquired by Queen City Brewing Co. and brewed for a little while longer out of Cumberland, MD and you see those 16 oz tabs all the time. Try finding one from Richmond, though. I think it's about a 100 : 1 ratio of Cumberland vs Richmond.

One tough one that I can't find is a 16 oz Blatz Flat from Peoria. Not very valuable, but you just don't see these, and even harder to see a nice ONE. I need an upgrade if anyone has one :-)

Great to see this old thread still running. I'd like to add two cans for consideration. The Natty Bo from Miami is tough and I'm told the only one known but hope somebody can prove otherwise. Jim Wolf already added it to the USBC Supplement Vol 2. The other one was a paintover. It looks like it could have been under a Canadian Ace because it has a "extra strong" and Canadian Ace Brewing on the lid. I think @Leon made mention of a Colt 45 flat top from Detroit but it has not been added to the USBC Supplemental Vol 1.

@storzman Eric....your thoughts.....

Heres my two Richbrau 16s

I don't have a lot of pint cans, but these are some of mine. All are flats except for the Richbrau (which is the Richmond one). The Gunther is a "Display Empty" can.
