Josef V. Scheybal was a significant exponent of Czech ethnographic drawing. His documentary work was based on both his profound knowledge of the field and his highly developed technical skills. His drawings display mathematical accuracy and precise details, but they remain compositionally and technically convincing. Josef V. Scheybal substantially contributed to the documentation of folk architecture in Northern Bohemia, mainly in the areas along the Jizera River and beneath the Giant Mountains where he participated in several field research projects (i.e. in the environs of Český Dub, Liberec, Železný Brod and Jablonec nad Nisou). He made thousands of drawings which are often the only documents we have of defunct and destroyed monuments (not only folk structures). Compact sets of his archived documentary drawings are often employed in museum and topical exhibitions and in the collection of data for folk art encyclopaedias (the Encyclopaedia of Folk Art) and ethnographic publications (A Key to the House - Folk Structures of Eastern Bohemia, Wind Mills of Moravia and Silesia).

Josef V. Scheybal was also a talented illustrator and in his youth he illustrated several works of belles-lettres. We must also mention his landscape paintings.

The author's theoretical activities reflected his interest in ethnography and fine arts. His writings include two art monographs dedicated to the painters A. Kašpar and M. Votrubec. He also devoted himself to the history of Northern Bohemia and folk architecture, especially in the area along the Jizera River, and he published national history works together with his wife.

Jana Scheybal's field of interest included regional history and topography. Together with Josef V. Scheybal, she published The Art of the Folk Carpenters, Stonemasons and Sculptors in Northern Bohemia (1985), The Landscape around the Jizera River (1995) and Through the Landscape of Glass and Costume Jewellery (1998). Her own published works include The Folk Culture of North Bohemia (2006), The Bohemian Paradise of Josef Pekař and His Contemporaries (2006) and the Bohemian Paradise in Old Slides (2007).
