Question: Sometimes called fabulism, what genre of art was Alexander Kanoldt known for?

Context paragraphs:
Magic realism: Magical realism, magic realism, or marvelous realism is a genre of narrative fiction and, more broadly, art (literature, painting, film, theatre, etc.) that, while encompassing a range of subtly different concepts, expresses a primarily realistic view of the real world while also adding or revealing magical elements.  It is sometimes called fabulism, in reference to the conventions of fables, myths, and allegory.  "Magical realism", perhaps the most common term, often refers to fiction and literature in particular, with magic or the supernatural presented in an otherwise real-world or mundane setting.

Naïve art: Naïve art is any form of visual art that is created by a person who lacks the formal education and training that a professional artist undergoes (in anatomy, art history, technique, perspective, ways of seeing).  When this aesthetic is emulated by a trained artist, the result is sometimes called "primitivism", "pseudo-naïve art", or "faux naïve art".  Unlike folk art, naïve art does not necessarily evince a distinct cultural context or tradition.  Naïve art is recognized, and often imitated, for its childlike simplicity and frankness.  Paintings of this kind typically have a flat rendering style with a rudimentary expression of perspective.

Art theft: Art theft is usually for the purpose of resale or for ransom (sometimes called artnapping).  Stolen art is sometimes used by criminals as collateral to secure loans.  Only a small percentage of stolen art is recovered—estimates range from 5 to 10%.  This means that little is known about the scope and characteristics of art theft.

History of fu poetry: The History of "fu" poetry covers the beginnings of the Chinese literary genre of "fu".  The term "fu" describes literary works which have certain characteristics of their own.  English lacks an equivalent native term (or form).  Sometimes called "rhapsodies", sometimes called "rhyme-prose", "fu" are characterized by qualities of both poetry and prose: both are obligatory.  The "fu" form of literary work is a treatment in a poetic manner, wherein some topic (or topics) of interest, such as an exotic object, a profound feeling, or an encyclopedic subject is described and rhapsodized upon, in exhaustive detail and various angles of view.  And, for a piece to be truly considered to be within the "fu" genre, it must follow the rules of this form, in terms of structure, meter, and so on.

Art of the Upper Paleolithic: The art of the Upper Paleolithic is amongst the oldest art known (sometimes called prehistoric art).  Older possible examples include the incised ochre from Blombos Cave.  Upper Paleolithic art is found in Aurignacian Europe and the Levant some 40,000 years ago, and on the island of Sulawesi in Indonesia at a similar date, suggesting a much older origin perhaps in Africa.  Cave art in Europe continued to the Mesolithic (at the beginnings of the Holocene) about 12,000 years ago.  As this corresponds to the final phase of the last glacial period, Upper Paleolithic art is also known as "Ice Age art".

Art handler: An art handler, also sometimes called an art preparator, is a trained individual who works directly with objects in museums, art galleries and various other venues including private collectors, corporate art collections, public art collections and various other institutions.  Art handlers work in coordination with registrars, collection managers, conservator-restorers, exhibition designers, and curators, among others, to ensure that objects are safely handled and cared for.  Often they are responsible for packing and unpacking art, installing and deinstalling art in exhibitions, and moving art around the museum and storage spaces.  They are an integral part of a museum and collections care.

Trot (music): Trot (Korean 트로트 "teuroteu"; sometimes called 뽕짝 "ppongjjak" due to its distinctive background rhythm) is a genre of Korean pop music, and is recognized as the oldest form of Korean pop music.  Formulated during the Japanese rule in the early 1900s, the genre has been influenced by Japanese, Western and Korean musical elements.  Also, the genre has adopted different names, such as "yuhaengga", "ppongjjak", and most recently "teuroteu" (the Korean pronunciation of the word trot).  While the genre’s popularity declined during the 1990s, most recently, it has been subject to revivals by contemporary South Korean pop artists such as Jang Yoon Jeong, Super Junior-T, BIGBANG member Daesung, Red Velvet member Joy, and Trot Queen Hong Jin-young.

Genre painting: Genre painting, also called genre scene or petit genre, depicts aspects of everyday life by portraying ordinary people engaged in common activities.  One common definition of a genre scene is that it shows figures to whom no identity can be attached either individually or collectively—thus distinguishing "petit genre" from history paintings (also called "grand genre") and portraits.  A work would often be considered as a genre work even if it could be shown that the artist had used a known person—a member of his family, say—as a model.  In this case it would depend on whether the work was likely to have been intended by the artist to be perceived as a portrait—sometimes a subjective question.  The depictions can be realistic, imagined, or romanticized by the artist.  Because of their familiar and frequently sentimental subject matter, genre paintings have often proven popular with the bourgeoisie, or middle class.

Alexander Kanoldt: Alexander Kanoldt (29 September 1881 – 24 January 1939) was a German magic realist painter and one of the artists of the New Objectivity.

Conceptual art: Conceptual art, sometimes simply called conceptualism, is art in which the concept(s) or idea(s) involved in the work take precedence over traditional aesthetic, technical, and material concerns.  Some works of conceptual art, sometimes called installations, may be constructed by anyone simply by following a set of written instructions.  This method was fundamental to American artist Sol LeWitt's definition of Conceptual art, one of the first to appear in print:
