Hand-knotted in pure wool and originating circa 1980-1989 from Denmark, this rare 6x6 square carpet joins Rug & Kilim’s Mid-Century Modern collection. Inspired by Piet Mondrian's iconic original design of 1921, signed “PM 21” and made by Ege Axminster, this field features geometric De Stijl design with black grid lines and primary red, yellow, blue, and white/cream colors. On the Design: Conceived in homage to De Stijl pioneer Piet Mondrian, this Danish textile translates iconic 20th-century Neo-Plasticist painting into a compelling work of floor art. Emerging in the Netherlands, Mondrian's revolutionary philosophy sought pure abstraction by stripping artistic expression down to its fundamental elements: straight vertical and horizontal lines anchored by primary colors and non-colors. Neoplasticism was the core aesthetic philosophy of the Dutch “De Stijl” movement, pioneered by Piet Mondrian to express pure harmony through absolute abstraction. This painting style strictly limited its visual vocabulary to straight horizontal and vertical lines, rectangular forms, and a basic palette of primary colors alongside black, white, and gray. Mid-century Scandinavian designers frequently looked to European avant-garde movements, reinterpreting minimalist canvas masterpieces into floor coverings. The square format provides an ideal spatial medium for this geometric harmony, requiring precise artistic balancing so the gridlines unfold in natural proportion across the field. Free from artificial ornamentation, this vintage piece stands as an exceptional collector's item for enthusiasts of mid-century modern design and modern art history. The field displays a dynamic rectilinear grid composed of bold black structural lines that divide the off-white background into asymmetric compartments. Prominently featured across the upper and central sections are large saturated blocks of primary red and canary yellow, balanced by a deep cobalt blue block along the lower right edge. Subtler charcoal grey and soft parchment rectangles add sophisticated visual weight to the left quadrant, while a hand-knotted signature and date reading "PM 21" anchors the lower edge. The juxtaposition of primary hues against neutral off-white spaces creates a striking visual cadence, drawing the eye across the geometric field with rhythmic momentum. Designed to anchor minimalist, contemporary, and mid-century architectural spaces, this square rug serves as a magnificent art-focused centerpiece for modern living rooms, executive suites, and gallery interiors. Condition: This signed vintage Mid-Century Modern rug is in good condition for its age and origin.
