I have a litho graph picture showing half man half goat, one man goat is carrying a sheep on his shoulder other goat like men are sitting in the forest. Another person dressed in orman tyoe toga is with two other goat men. It is very old.

No one online can help you (with it's value?) without at the very least a picture front and back, but that's not enough either. Paper has to be examined, and the tiny lines of ink. Take it to an art dealer.
