Signed Italian Religious Silver Picture Shadow Box Style of Mary Joseph Baby

Italian Religious Silver Picture Shadow Box Style of Mary Joseph Baby Jesus, signed Salerni, measures 15.5" by 13.5", shadow box type of style with raised images. It is marked An Ag 5g 22 ASA. I looked these up and what I could find out was "An" was for Ancona, Province in Italy where it was made. "Ag" chemical symbol for silver, "5g" indicates there is 5 grams of pure silver used in the laminated layer of the plaque, "ASA" Brand or maker's mark, often produced by Italian firm ASA Linea, and "22" indicates silver plating thickness or the silver smith's code. There is a small part on the frame that I have pictured where it had a touch up on it. Overall, I don't think it is very noticeable. Please, if you have any questions, please ask, thank you.
