These exceptional original drawings, painted with colored pencil on translucent tracing paper, were designed by a French artist, circa the 1960s. The two rare paintings feature a geometric study of stylized robots, rendered in various colors. The compositions feature hypnotic repetitions of stylized geometric shapes, rendered in shifting gradients of color that evoke a sense of movement and mechanical harmony. This chromatic exploration appears to seek an ideal convergence of form and palette—a study in joy, balance, and the rhythm of structure. These two drawings were purchased in France in 2005 at a private estate sale as part of an important portfolio of sketches, all created on tracing paper with black pencils and some with colored pencils. The portfolio was dated from 1963 to 1968. These surreal designs feature a repetitive geometric shape with gradient colors, characterizing a subtle interplay of shapes and tones. The goal of this study's aesthetic investigation, which involves color alternation, is to achieve the ideal balance between form and color, thereby creating a joyful visual experience. The palette is bright, the geometry dominates, and the colors are juxtaposed to underline the rigor. Set against a vibrant color palette, the works strike a balance between mathematical clarity and artistic playfulness. Framed in sleek black wood with a gray-and-black matte and protective glass, they present as both modern and timeless, equally compelling in a contemporary interior or mid-century design collection. There is no visible artist signature. The artwork is framed in a contemporary black wood frame with gray and black matte and glass protection.
