I have two very large prints, framed, which I purchased 35 years ago. One is called "Ruth and Naomi" and does not have the waiting figure in the background which the color painting has. It has an imprinted signature P. A. Calderon. The other is called "The Wedding." It has an embossed seal but no other information. They appear to be by the same artist, but I can find no reference online to prints by Calderon or an original called "The Wedding." It appears to be of the same genre -- Biblical -- and the male figure has an animal skin as part of his clothing. Can you tell me anything about them?
