Antique Petit-Point Portrait of God or Saint, From London, Church popular Relic

This is a beautiful antique needlework portrait of a religious figure, since he has a gold halo, probably a saint or God

It is in its original wood frame, which is quite worn - but still holds together

The outer dimensions are 15” x 12.25”

Estimating this piece is from the mid to late 1700's, from England

There are a few bits of writing on the back of the frame. One word is clearly “London”, I cannot popular make out the others (there are close up photos for your reference)
