This idyllic scene is an "escape picture", a visual tool to help you project somewhere else.
This painting will be chosen for the satisfaction it brings to your "space".
"Unknown artist" is appropriate when a work of art is unsigned and a supported opinion about who made it is not available (on Savvy Collector).. "Attributed to" precedes the name of an artist when information suggests that it likely was made by that artist (on Savvy Collector).
