Thought provoking picture...
Is the hand white or Yellow and is it on 'top'? (See buddhagurl8's comments in the Global Gallery)
Look again - it comes from the upper part of the painting but holds the lower part of the globe - while the other, emerging from where the race is most dominant, comes from the lower part of the picture to hold tight to the upper part of the globe - One world, One Unity irrespective of where one comes from, Peace is universal...
As to clothes - its reflective of the dominanat cultural attire - the peoples of the South predominantly do not wear long sleeved clothes and the Peoples of the North do...probably has a lot to do with the weather...:-)
Note that both 'were' bound by fetters of iron which are partly broken...my question would be where is the source/origin/beginning of this? Who 'secures' it?
The Globe with the hands is such a poignant picture filled with mysteries it largely over-shadows the presence of the myriad races reflected behind, the scroll with 'Rights' clearly visisble and the symbols of equal justice above; and the shadow figures underneath.
I see the deeply affected Africa, haltingly held together by 'band aid'...striking right through its heart and civilisation...it brings to mind Chinua Achebe's masterpiece...'Things Fall Apart and the centre cannot hold, Mayhem, Anarchy is loosed upon the land'...A result of mans' inhumanity to man...
Will the world survive its present mayhem? For a time and a season yes - but we have too look inward before we totally self-destruct...

Faith...Hope...Love...Unity...Peace
