Belgian art dealer Klaas Muller purchased a painting at an online auction three years ago, identified only as a study by an unknown artist of the Flemish school. After research, he discovered the work is likely a rediscovered study by Peter Paul Rubens (circa 1609), featuring a hidden second image of a woman's face visible when the painting is turned upside down. The work will debut at the BRAFA art fair in Brussels, where Muller serves as chairman.
Belgian art dealer Klaas Muller has identified a previously unattributed oil-on-paper study as a work by Flemish master Peter Paul Rubens, titled "Bearded old man, looking down to his left" (ca. 1609). Muller purchased the piece for under €100,000 at a lesser-known northern European auction house three years ago, where it was listed as an unknown artist from the "Flemish school." After recognizing the bearded figure as Saint Thomas from Rubens's "Apostolado Lerma" series at the Prado, Muller commissioned research from art historian Ben van Beneden, former director of Rubenshuis, who confirmed the work's exceptional quality and likely attribution to Rubens. The study also features a ghostly woman's face visible when turned upside down, reflecting Rubens's playful reuse of materials.
