The Majolica International Society posted some lovely photos on their Facebook page of two American themed majolica pieces for the Fourth of July.
Aside from these two Copeland examples I can only recall seeing a couple other pieces with an American historical theme: the Wedgwood Washington-Lincoln Centennial pitcher and the John Garfield memorial pitcher.
That doesn't seem like a lot considering how large the American majolica market was at the time.
If you can think of any others please drop me a line.
Have a happy and safe 4th of July!
