Finding this etching, deciphering the signature lead to forgotten Jewish Vienese etcher Guido Grünewald. He started his artistic career late in live and was short-lived. He died shortly after his print of a sleeping kitten cat became world famous as Chessie in America. Read about this amazing story and the connection to one of the worlds first women Daguerotype photographers with branches in Germany, Italy and New-York in the accompanying Biographies Book (and PDF) and as an exception in the pop-up under the title of this entry (above).
