Valentin Serov - Portrait of Princess Olga Orlova (oil on canvas, 1911)
"A Game of Diabolo" by Leopold-Franz Kowalski. Undated (likely late 19th century), oil on canvas. Substantial in size at approximately 73" x 49". I know nothing about this artist but this is a very pretty painting. In a different mood the use of pink for sunlighting might strike me as a bit twee. Auctioned 9 May 2014 at Sotheby's NY. Pre-auction estimate: $25,000 to $35,000. Auction results list indicates the painting was "withdrawn, passed or unsold".
