Brave Fine Art has dated this piece to the 19th Century.
The artist, Johannes Boesen (1847-1916) was highly regarded during his lifetime and won numerous awards. He was fortunate enough to train under the great P. C. Skovgaard (1817-1875) - one of the foremost Danish Golden Age painters.

Boesen's style is rooted in the Danish Golden Age tradition yet his brushwork is a little looser than his mentor’s. Like many Danish painters of his generation, his work became more impressionistic towards the end of the 19th-century.

Several of his paintings have sold through the leading auction houses and here are a few examples.
