Beautiful illustrated Secretariat postcard signed by three key members of the team behind the legendary 1973 Triple Crown champion. Card measures 4x6" with the illustrated portion at 4.75x3.75", and is signed by Ron Turcotte in 6/10 black ink (Turcotte is pictured atop "Big Red" in the image), trainer Lucien Laurin in 3/10 ink, and owner Penny Tweedy signed in 4/10 black. Back has printed detail noting that it is from a portrait in the National Museum of Racing in Saratoga Springs, and there are a few small areas of clear tape residue on the otherwise-blank back. Encapsulated by PSA/DNA as AUTHENTIC AUTO for all three signatures.
