Royal Standard of Israel

Here's how I would imagine the flag of the King of Israel if it had been founded as a Kingdom rather than a Republic, and ruled by a Neo-Davidic Dynasty.

Above the Emblem of Israel is the Crown of David, with added arches and beret (mostly to make it look more interesting.) Dimensions based on the flag of the Kingdom of Italy.
