But seriously, study of flags is known as vexillology. The word comes from those big one-sided banners the Romans (and possibly organizations like the Orangemen and the National Union of Mineworkers) used to carry at parades, demonstrations, rallies etc: the name for this sort of banner was a vexillum.
Flags however, are meant to be viewed from either side. And so the designs have to be a bit different from those on a vexillum.
