Behind each object, there is a creation, a reflection, a conception. Deviate it from its purpose, give it a name and you will get a "work of art".
Marcel Duchamp assumes that tearing a product away from its classic utilitarian function to expose it in a pure form leads the viewer's gaze to take an interest in this object for itself.
It's not a bag! "It's art": you have to see beyond the simple object; behind each bag, an artist sleeps.
