Help, please, to determine whether the valuable painting

[Amateur]

Subscribe to "H. Jasper" could, in principle, three artists:

1) Heinrich Jaspers (1800 -?), Denmark
2) Henk Jaspers (1905-1977),
3) Jasper Holman Lawman (1825-1906), USA.

Here's how it really is. Last signed "Lawman", or "J. Lawman". Second - "H. Jaspers", but in block letters. It signed the first, I did not find.

The variant, as in your first topic that the film "Made in China".
