The plaque depicts Sir Simon (Symon) de Felbrigg and his first wife, Lady Margaret Felbrigg, whose monumental brass is in St. Margaret's Church, Felbrigg, Norfolk, England.
The original monumental brass dates to about 1416, when Lady Margaret died. Museum and National Trust records describe the composition with Sir Simon in full armor beside Margaret beneath an elaborate Gothic double canopy.
Your plaque appears to be a 20th-century souvenir/reproduction plaque, rather than an antique brass rubbing or medieval object. The green felt backing, hanging hardware and printed “Hand Made in England” label are particularly characteristic of a decorative wall plaque intended for the heritage/tourist market.
The front inscription:
Sir Symon Felbrygge and his Lady
14th A.D. Felbrigg Norfolk England
The wording is somewhat simplified historically—the famous brass itself is generally dated 1416/1417, i.e. early 15th century, rather than the 14th century.
What the imagery represents:
Sir Simon was Sir Simon de Felbrigg (c.1367–1443), a Knight of the Garter and former standard-bearer to King Richard II. His wife Margaret was of Bohemian noble birth and had been a lady-in-waiting to Anne of Bohemia, Queen of Richard II.
The original brass includes heraldic shields, the Felbrigg badge, Richard II's white hart badge, and Simon's Order of the Garter, visible beneath his knee.
The banner he carries refers to his royal service. The lion at his feet is also a conventional medieval knightly funerary motif.
Dating: Mid-to-late 20th century, probably somewhere in the 1960s–1980s range.
