Sessions Clock Co. "Observatory Advertising Clock", touted as a good way to advertise a business or product. The "store regulators" were used everywhere. I have seen a hundred with "Calumet Baking Powder" advertising, but never one that was original. This old oak case is 38 1/2 inches high, has 2 old black and gold glasses. The top glass has a rainbow crack in the lower left corner. I sure wouldn't replace it. The old case is untouched. 8 day time and calendar movement, new paper dial. Ehrhardt, Book 1, page 184.
