bronze plaques

[joycew]

I have a rectangular "Last Supper" plaque which measures about 9" x 15", and it is marked in the lower right corner, "Made in England".  The back has a ten-link chain, with a circular piece in the center for hanging.  This picture is "framed" with the relief being hammered into a 3/4" frame surrounding the picture, and is also highly detailed in all other aspects, and is in excellent condition.  Can anyone help me with its age and value?
