A lubok (plural lubki; Russian: лубо́к, лубо́чная картинка) is a Russian popular print, characterized by simple graphics and narratives derived from literature, religious stories, and popular tales. Lubki prints were used as decoration in houses and inns. Early examples from the late 17th and early 18th centuries were woodcuts, followed by engravings or etchings, and from mid-19th century lithography. They sometimes appeared in series, which might be regarded as predecessors of the modern comic strip. Cheap and simple books, similar to chapbooks,[1] which mostly consisted of pictures, are called lubok literature (Russian: лубочная литература). Both pictures and literature are commonly referred to simply as lubki. The Russian word lubok derives from lub - a special type of board (secondary phloem) on which pictures were printed.
