Egg Cooler Thermometer: Glass Contained Advertisement

I would be interested in knowing the value of this Advertising Egg Cooler thermometer. I live in Michigan, not too far from Ionia, but have been unsuccessful in creating any interest locally. My understanding is that it is rare. The patent number as shown on the advertising insert is 1,868,911 which dates it to July 1932 according to my sources. The phone number has only 2 (two) digits. It is in great condition. The lid has a bit of surface rust. I do not have the original container which I believe was round.
Thank you for your time and interest.
