Hello!

I have heard of a piece of what I believe is quite an old piece of
Catholic art. It depicts God (maybe shown as Jesus, not sure) with a
scale in front of him. The scale has Mercy on one side and Justice on
the other, and I think you get the idea that he is judging a
particular person. The Blessed Mother (Virgin Mary) is shown sort of
sneaking behind him, or perhaps standing next to him, placing her
finger on the "Mercy" side of the scale, so as to advocate for the
person being judged. Can you help me find the name of the piece, the
artist, and where I could get a copy? THANKS!!!
