Our advertising clocks are made from old clock cases from the 1950's. The most common type I use is a marquee clock made by the Ohio Advertising Company and Lackner Clock Company. Both were made in Cincinnati Ohio and stained glass fits in them perfectly. They make nice night lights also. Most of these have a Clear lake, Iowa theme but I can also do custom clocks. Some have a rare neon spinner and these are very hard to find and add to the cost.
