I have found what I think is the bottom section of a 2 piece Conoco sign. The pole is rectangular in shape. It's about 11ft tall (hard to measure with a tape measure in the Kansas wind), and the base measurements are 18 1/2" by 21 1/2". The base is covered by 2 "U" shaped pieces of sheet metal to give it a finished look. All I have are cell phone pictures. Does someone have a similar Conoco sign/base pole that they could measure, or me send my pictures to them? Thanks in advance J. Patton Tribune, Ks.
