I picked up this rotating calendar at a Seattle telephone show last month.
This calendar was more than likely a give away item by Automatic Electric Co. which was the manufacturing arm of GTE. The base is stamped Brown & Bigelow patent pending ST. PAUL, MINN. I later found out the calendar was Patented by Charles A Ward on July 16, 1929
and assigned to Brown & Bigelow. I added the patent page.
