Yes, it is what first struck the curiosity of my husband about this painting. Tanguy illuminated the objects directly with collimated light creating distinct dark shadows (umbra) with no penumbra nor antumbra. This way it's like he's giving them an almost volumetric life of their own. Very interesting!The painting has a few shadows that are whole forms as opposed to the disparate objects the light hit to form the shadows...
We think that he got influenced in this aspect by Giorgio De Chirico.
