The studio of Piet Mondrian were works of art of them selves. They acted like a true work “in situ” where every item had its proper place . Because of this, the studio itself became a work of art. This was recognized by many and one of the greatest photographers from last centur even made a series of photo from the Paris studio. The same with the NY studio which was photographed by Arnold Newman.
Kertesz and Newman , two great photographers who realized that Mondrian was a very special painter and made these photographs with one purpose….. so we could see the extraordinary qualities Mondrian had when he approached a painting or an object.
There is onegreat article on Artsy where the studio’s of Mondrian are described.
