Today is a Daily Photo theme day, and the theme this month is "A Public Mail Box". I spotted this one in Kloofnek Street on Friday, and believe it may well be the oldest postbox in the city. It's located outside the Kloofnek Grocer; the shopkeeper wasn't sure why it had never been replaced, but she did mention that we're not the only ones who've stopped to take photos...
Does anyone know what the letters "GR" stand for? I know it has something to do with the British Royalty, but I'm not sure exactly what, and can't seem to find any info on the Web.

66 Daily Photo sites are participating in the 1st April theme, "A Public Mail Box"; please use the links to below to visit them. Due to time zone differences and other factors, the theme photo may not be displayed until later if you are viewing early in the day.
