Imagine how long this sign's been marking the bus stop. In fact, it looks like this one's holding bracket corroded away at some point and has been replaced by a nice new shiny bracket - which is either silver or made from something that isn't quite as corrosive as steel.

Many years ago, probably up until around the time my dad was born (which was a long time ago, dad ;) ) Cape Town use to have a tram system. In 1935 the city introduced its first trolleybus (which looked a lot like the buses we know today) which gradually led to the tram system being decommissioned in 1939.
