An ornamented steel 'Brievenbus' (the Dutch word for mail box) like this used to be quite a common sight in many places in the city when I was a child. It's where we drop our stamped mails to post. Now we don't see them much. Many of them have long been replaced by a simpler mail boxes or disappeared all together as fewer and fewer people send snail mails these days.
Some of these ornamented mail boxes have become a museum exhibit, some -- like this one -- have become a decorative ornament put at some post offices as a reminder of the past.
Location: Bandung's main post office on Asia-Africa street.
