Typewriter works by Montserrat Alberich Escardívol (1912-1973). Her first exhibition was in 1929 (including the Don Quijote image above) and she continued to type graphics most of her life. The typewriter company Underwood gave her a customized typewriter in 1957, with a few custom characters and a width of 310 characters. Presumably, the Barcelona Cathedral image was made some time after that. She used around 20 colour ribbons, which helped to set her apart from many other typewriter artists.
