This is a white milk glass mug decorated with a palm tree, setting sun, seagulls, and the word "florida" in lower case rainbow striped letters. There is also a black and gold foil label that reads "Made in Florida." The base is embossed Oven Proof Made in USA. The mug is 3 1/4" x 3 1/4." It is not a shape I recognize, the rim is slightly flared outwards. The glass is a translucent milk glass, not a solid opaque. I think most likely it was made by Federal Glass. It is in excellent condition with no chips or cracks.
