Brave Fine Art has dated this piece to the 19th Century.
Reisacher was an interesting artist as he also trained in photography and had a studio in Munich.

This could explain why the gentleman here is looking directly at us with his body square on to the easel. It’s possible that the painting was based on an earlier photograph rather than painted from life.

He certainly has a look to him.
