A branded weather thermometer?

This one came to mind just as I went to close a window for the night and noticed the old branded thermometer (basically a plastic disc with a print on it on which a red spirit thermometer was glued to) my grandfather got mass-produced several decades ago as promotional item for his flowers shop(!!!) which has been hanging forever outside the house.

Not quite sure these things are even produced any more, but it still seemed relevant enough to mention. ^^'
