Cubist painting : PARIS

Very interesting oil on wood. Nice cubist work. Monogram W in a circle (or in a "O" letter).
Paris view with Eiffel tower and Ferris Wheel just on the left. This ferris wheel was build at this place for 1900 Exposition Universelle and demolished in 1937. We can reasonably think that the painting is pre 1937.
21cm x 18cm ( 8.25" x 7").
