Vintage Hamm's Beer Sign "Mock-up Panel": Hand Painted - America's Classic Premium Beer Since 1865.
I have some information on this Hamm's item, but not all. It appears to be a Hand Painted Mock-up Panel for a Hamm's sign from the 1970's or 1980's. If you look closely, you will see that the words "Hamm's Beer" in red appear to be hand painted by an artist. I have taken pictures from various angles to show how it is painted rather than printed. The red painting appears only on one side of the panel. Blue paint has also been included in a random fashion. 
 This is a panel for a Hamm's sign which is not lighted. I have included a picture of this sign only for visual information. IMPORTANT: This Hamm's sign pictured IS NOT INCLUDED IN THIS AUCTION. ONLY THE PANEL IS INCLUDED.
Wording in white on blue says "America's Classic Premium Beer Since 1865".
I have no further information on this panel. Please judge for yourself. This being the case, I have started this auction at the opening bid of $19.99.
It is certainly a unique piece. May be one of a kind.
