We present an exceptional folk art piece – the painting "Typhoon over California" by Regina Hejnowska, executed in the traditional technique of painting on glass. This is a rare and highly decorative example of Polish folk creativity, combining a traditional form with an original, vivid interpretation of the subject. Painting on glass is one of the most distinctive and valued techniques in art, requiring from the artist not only painting talent but also immense precision, because the paints are applied to the reverse side of the glass pane, working from details to the background. The offered painting showcases the intensity of colors, clarity of contours, and a specific "nobility" of color typical of this medium, resulting from light shining through the layers of paint. Regina Hejnowska is a recognized representative of Polish folk art, and her works are characterized by an individual style, often referencing natural and landscape motifs with elements of fantasy. "Typhoon over California" is a fascinating combination of a local technique with an exotic, dramatic scene, giving the work a unique, collectible character. This is an ideal proposition for lovers of authentic folk art, collectors of Polish non-professional art, and those seeking unique decorations for their interiors, saturated with history and handcraft. The painting is not only a beautiful decorative element but also an important trace of cultural heritage.
