Are Tyrrell prints usually signed by drivers or artists?

Many Tyrrell prints are signed by the artist as standard practice, which confirms authenticity and adds collector appeal. Some editions include signatures from drivers such as Jackie Stewart or Jody Scheckter. Multi-signed prints can feature both the artist and a driver, which tends to increase value. Signed editions are often limited to smaller runs, sometimes under 200 copies. Authentic signatures are typically added during official signing sessions arranged by galleries or publishers. Certificates of authenticity often accompany these prints. Unsigned editions are more affordable and widely available. Signature placement varies, with some artists signing in pencil below the image and drivers signing within the artwork area. Collectors often verify signatures through comparison with known examples, especially for higher-value pieces.
