A Woodland Stream, Peder Mørk Mønsted
Link is to Wikimedia Commons, which has a high res version of the file. The original was sold through Sotheby’s in 1987 and is presumably still in a private collection.
As far as I can tell, the majority of Mønsted’s paintings seem to be in private collections. He is one of my favorite painters, based solely on seeing images of his work; I’ve never seen an original in person.
If anyone is aware of Peder Mønsted paintings in public collections here in the U.S. (particularly on the mid-Atlantic states), I would love to know about them.
