Flying the flag

Many flags have to be flown the right way up, as mentioned in a previous post Distressed or 'in mourning'?

But did you know that only one country has a flag which is not the same on both sides.  Paraguay's flag has a distinct front and back (although it might be difficult to spot that from a distance when the flag is flapping in the wind).
