Albert Claes-Thobois, sometimes signed Claes-Florian, was a painter and watercolorist, with a predilection for stil lifes, cityviews and flowers.
He made drawings and woodcuts as well, illustrating “ Les heures d’après-midi” from Emile Verhaeren (1923).

As many painters in Belgium, he enjoyed his formation at the academie of Brussels under C. Montald and H. Richir.
Eventually he started in a very own interpretation of impressionism, to evolve from 1920 onward, to a certain Synthetic Cubism.
He exhibited in 1922 at the famous avant-garde Galerie le Centaure.
The Galerie George Giroux auctioned serveral of his paintings in 1947 and 1949.
Six works are preserved in the Museum of Fine Arts of Brussels.
