I guess curious are souveneres: one only buys them when they visit a certain place...as proof that they visited. Therefore, while tourists will fall over one another at "Maasai Markets" in town, you will not find the same enthusiasm if you try to export the curvings.
I know many have tried, but without much success.
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
