Hi, I am guessing more than that I am sure about the reading of the handwriting, but I think it could read like this: "gemalt & gewidmet seinem l. Sohn Adolf Zundel von seinem Papa München d. 31. Dezb. 1879" wich means: " painted & dedicated to his beloved son Adolf Zundel by his dad. Munich, 31.12.1879". So it is not a painters signature. About Adolf Zundel I do not know anything. However, it seems to be really nicely painted. Is it on porcelain?
