Great early German porcelain doll by Cuno & Otto!  This doll is 15 inches tall!  Looks like he is in his original blue sailor suit!  Suit is pretty faded, and has some stains.  Doll looks in pretty good shape!  Don't see any breaks or damage!  The hair looks kind of thin, like probably missing a bit and there is some short pieces on top like maybe it had gotten cut.  Back of neck looks like it says:  C. 0 1/2.  I do not know much about dolls and what you look for, so please ask questions!
