that picture is actually hail selassie's hands. haile selassie would always and pretty much would gesture his hands in this way to symbolize the seal of solomon (star of david) to siginify that he was in direct lineage of king david through solomon and the queen of sheba in union, whom they bore a son named menelik (son of the wise man). you see all rasta holding up this symbol with their hands to emulate the way of abbabjoni. but most of all rasta do this to represent that they are the israelites.
