Italian Raised Silver Art Style Picture

Very unusual picture. Raised relief silver/metal artwork picture, almost 3D effect, depicting skeletal figures in boats on a river. Wooden Frame. Paolo Schiraldi/Silvio Zippoli style, think it is a reproduction of an Italian made orginal. It may be sterling silver but can't be sure, looks like a 925 stamp on it but the stamp is very blurred. Could be silver plated. Appears to have some age to it either way and it is definitely a talking piece! In overall good condition, a little bit of wear and tear. Overall width is approx 43.5 cm by 34.25 cm height as framed.
