brass grave rubbings

I have two of these framed brass tomb rubbings. I am told they are from 1920's and rubebd from a cathederal in England. My very preliminary searches have shown that rubbings were outlawed many years ago ue to them defacing the original crypt plates making them of significant value. I cannot locate any in the north east Floria region. I am not sure if it is lack of interest or lack of items. I have a matching set of a "knight" and a "lady". I have uploaded the picture of the lady one only. The rubbing is on one sheet of parchment, cut out VERY cleanly and placed onto a mat type sheet. There is no tape or glue and look as though they were professionally framed some time ago. The glass lookes to be an older type of glass.

Good
