This is for the pair of busts. The dimensions are 4 inch diameter base, approx. 7-1/2 inches wide. The girl is approx. 12 inches tall. The 

boy is approx. 11-1/2 inches tall.  I am not sure who the sculptor was. The initials G.F. are embossed on the bottom. There is a Houdon 

name cast in on the backs.  The couple of very small paint chips are hard to see on top of the girl's head.   See Pictures.
