This aerial photo by G.D. Fronabarger of the SEMO District Fair is noteworthy for the air marker on the roof above the grandstand at the Arena Building. The undated photo was taken on a day of harness racing and may be from the 1940s.
The air marker shows the city's geographical coordinates: latitude 37 18 N and longitude 89 32 W with an arrow pointing north. Another arrow and a "5" points toward the airport.
The Southeast Missourian archives show other air markers were painted in the city:

One of the things given attention was air markers for Cape Girardeau. There's but one left--painted on top of the Arena Building, the other marker disappearing with the burning of Houck Field House. Letters are to be addressed to owners of buildings here which have large roof areas, suggesting that these owners could advertise their business and the city with appropriate signs.
