"Flair" by Saul Steinberg, 1950). I love that this piece shows how collage can be experimental and translate to the real world through Steinberg's real-life drawing on the walls to create this collage. This captures a sense of playfulness and humour that makes the piece more complex than a simple 3D collage. The use of just two materials is interesting, as the piece uses other complex ideas such as depth and space that add detail and interest to the piece.
