The Flag Code

In the Bible we often read about Father Abraham and his many descendants but we don't get to realize this in reality.So, going for a walk along the busy Biashara Street I happened to get a glimpse of some beautiful flags ranging from different sizes to different designs.
Some were in sticker form,others as badges and some in banner style.Flags have also slowly evolved from the patriotic approach to a trendy and social statement in the form of fashion,marketing and vehicle aesthetics.
I know some guys who have included them as part of interior design.Anyway,for every flag there is a conviction or symbolism behind it,One that unites a specific country or a group of people.
Now checking at the various flags we have in the African continent,one is amazed with the variety.
To simplify the process it's better to group them according to the items and colours placed on them:
