Here's some information I received after a query in Stedelijk Museum in Amsterdam:

"We have a catalog of the exhibition. Artworks Mashkov (Machkoff, as written in the catalog) are numbered 131 to 142, on page 39. There is just one black-and-white illustration № 137," Naked. "Only one painting" Flowers " ("Fleurs") (Directory in French) under number 139. Dimensions and machinery not specified. Just - "Flowers". "
