Un rêve 

"Un rêve" is a Cubist drawing by Louis Marcoussis, created with graphite pencil. The abstract composition features intersecting geometric forms that create a sense of depth and fragmentation. This fragmented and seemingly disconnected approach is characteristic of Cubist artworks, which sought to break down traditional representational forms and explore the idea of multiple perspectives. The drawing's title suggests that the artist was exploring dreamlike imagery and the subconscious through this abstract composition.
