An important woodcut by František Kupka from his celebrated 1926 portfolio Quatre histoires de blanc et noir (Four Stories of White and Black). The present work is securely identified as Plate No. 14. An identical composition is represented in the Metropolitan Museum of Art, New York, where the block dimensions are recorded as 20.5 × 15.5 cm, precisely corresponding to the dimensions of the present impression. The composition is constructed from delicate geometric lines converging, diverging and intersecting across the pictorial field. Through rhythm, direction and repetition, Kupka creates a remarkable sense of movement, spatial tension and internal energy without relying on traditional representation. The portfolio represents a crucial stage in his exploration of an autonomous abstract visual language. Plate No. 14 is of particular interest within the history of the portfolio, as additional variant impressions of plates 14 and 20 are documented in deluxe examples of Quatre histoires de blanc et noir. Printed on handmade paper with characteristic irregular edges. Mounted, framed and glazed. Provenance: extensive private Prague collection. CURATOR'S TIP: An especially interesting Plate No. 14 from one of Kupka's key graphic cycles, securely identifiable through museum examples and distinguished by the documented existence of variant impressions of this particular plate. INVESTMENT RECOMMENDATION: Original prints from Kupka's major graphic cycles offer collectors an opportunity to acquire an authentic work by one of the pioneers of international abstraction. The precise identification, 1926 dating, handmade paper and distinguished provenance enhance the collecting appeal of the present work.
