This poster only uses simplified grids with black and white colors. I am really attracted to this minimalism style. Most of the situation, the simpler the shapes are, the harder it can be made into a good-looking design. The designer behind this poster is called Joseph Muller. The most amazing part of this poster is the circles. They seem to be put randomly on the poster, but there is actually a principle applied on them. The biggest circle is only shown a quarter of it and all the circles are connected in 45 degrees. The small details actually help to form this great work.
