To test radiocarbon dating, Willard Libby borrowed objects with verified ages from museums, including a sandal found in an Oregon cave.
Notes on verification
Confirmed by University of Chicago news office, Libby's own Nobel lecture, and independent Oregon archaeological sources (Fort Rock Cave sandals dated ~1949-1951).
