This is a very good Crystoleum picture in its original gilt frame, by J H Schroder, a German artist. (Johann Heinrich Schröder (German, 1757-1812))
The picture shows a family eating at a dinner table. The ruff collar points to a setting in Elizabethan times, but this is a late Victorian Crystoleum. 
The process of making crystoleum's was popular from around 1888 to 1915. 1000's of examples were produced but only a few survive.
The crystoleum is mounted in its original 19th Century gilt frame.
This picture is signed in the lower left hand corner.
