It is gouache on board, with small surface faults, see black ballet shoe at left, left of chin of the girl in the foreground and a couple of similar faults. The vertical pencil mark that was present when photographed (upper left corner) has been removed without damage to the image. 

Heavy craquelure in particular to the petal areas, we would suggest having this area professionally stabilised. Frame with a couple of minor scuffs and losses to the gilding to be expected with a painting of this age.
