VIET NAM PAPER MILITARY MONEY

Among the many items just donated to the Archives of The Museum of the San Fernando Valley recently by Jerry Berns is this paper nickle distributed for use during the Vietnam war.
Paper coin-denominations have been long issued by the American government for military usage. (I have a paper quarter found in my great grandfather Josiah Crites' Civil War "picket duty" reminder book.) The use of paper money makes sense from the perspective of weight but also because of its noise factor.
Who do you suppose the lady with the fancy hairdo is?
