Garage find that has been in place for over 30 years that I know of. The plastic/celluloid frame is faded/yellowed with age and whatever fumes were in the garage. It seems to be accurate and is just about 12 inch diameter. It needs a good cleaning but should be functional for years to come. I have found several similar thermometers online for prices ranging from $11 for a "basket" case to $89 for one that looks like new. I only hope to never see -60 degree reading however.
