Skippings Fine Arts has dated this piece to the 1920s.
Detthow appreciated the work of Paul Cézanne, and our painting testiifies to this. It dates from the mid 1920s - arguably Detthows best period, as a young and mature artist. It was in 1924 that Detthow was selected to be shown at the Salon des Arts Décoratifs.
Detthow studied 1912-1913 at the Royal Academy in Stockholm and 1914-1915 in Paris. He returned to Paris in 1919 and settled there.
. He was elected in 1920 as a member of the Salon d'automne in Paris and participated in their annual exhibitions, where he was also a jury member. He participated in the Salon des Tuileries from its inception in 1923, as well as st the "Salon des temps présent" . His work has been shown in exhibitions of French art in most European capitals. He is represented in the National Museum, Vänersborg Museum and Kalmar Art Museum.

Just for reference, one of the photos in the listing shows a smaller painting by Detthow, catalogued by a Swedish auction house with an estimate of ca £2000-2400.
Measuring 38 x 46 cm without its frame, our painting is painted on panel and signed at the lower left.
