Brave Fine Art has dated this piece to the Before 1700 period.
Following his execution in 1649, numerous portraits were produced in varying styles.
It appears to present him in his late 40s, which would match the style of his outfit - popular in the 1640s. Charles was born in 1600.

The portrait is notable for the particularly ruddy cheeks coupled with a sense of malaise in the eyes. It’s a quieter portrayal, reflective and sombre. Not particularly regal or grand. Here’s a King reduced to a mere mortal.

The work is an oil on copper and presented in a splendid giltwood scroll and foliate frame. A wonderfully historic piece.
