Impressed by the photomontage of the German Dadaists, Rodchenko began his own experiments in the medium, first employing found images in 1923, and from 1924 on, shooting his own photographs as well. His first published photomontage illustrated Mayakovsky's poem, "About This", in 1923. In 1924, Rodchenko produced what is likely his most famous poster, an advertisement for the Lengiz Publishing House sometimes titled "Books", which features a young woman with a cupped hand shouting "книги по всем отраслям знания" (Books in all branches of knowledge), printed in modernist typography.
