Description:
  • This 5 foot x 7 foot vertical dial is painted onto the true south facing concrete wall of a commercial building. The gnomon and hour lines appear to be weathered copper or bronze. The hour lines are corrected for longitude, but may be in error by about 5 minutes. The dial is in relatively good condition, but the painted numerals are fading. The building itself has been in several hands over the last 10-15 years.
