I met a very intelligent Anglican priest today, Paul Kinsey, who has The Curiosity Shop in Walsingham. He has a website which is here. His blog pages make mine look like kindergarten drawings.
Anyway, in his shop are wall paintings, immediately painted after the destruction of the shrine and re-found about 1995.
Paul noted that I probably would not be able to copy the photos from his site, but look here and read about the theme, which is an anti-Henry VII theme.

I highly suggest clicking on this link for a delightful view of the paintings with explanations.
