Four vintage ink signatures of recipients of the Nobel Prize in Physiology or Medicine on various slips and cards, including: Herbert S. Gasser, known for researching human nerve cells; Edward C. Kendall, the co-discoverer of cortisone; Philip S. Hench, the co-discoverer of cortisone; and Charles B. Huggins, who discovered that hormones could be used in treating cancer. In overall very good to fine condition.
