Lettrism
レトリスム / 1946–1970s / Style / Experimental Typography
A Paris-born movement that freed the letter from its duty of carrying meaning, treating sound and shape themselves as the material of the work. From surfaces paved with unreadable characters, to hypergraphy's proliferating signs, to marks scratched directly into film stock, it expanded the experiment of handling letters as physical matter.
Surfaces paved with unreadable characters / Handwriting mixed with type / Hypergraphy of proliferating signs / Letters handled as painterly material
