P.J. Redoute print

P.J. Redoute print Originally sold at Gordon Dunthorne etchings and old prints.
Picked it a an estate sale for a few dollars.
More research says that Mr. Gordon Dunthorne purchased a shop of etchings way back and .I think it exists today as the old print shop.
The label on the back suggests quality according to the addresses.
Has foxing .
I do not know if it is faded or needs a cleaning .It definitely needs the foxing removed or neutralized.
