I have a number of signed cards from that 1977 TD set - Danowski, Dudley, Flaherty, Friedman, Grange, Hein, Howell, Leemans, Nagurski, Poole B, Poole J, Soar, and Strong. The Friedman card has a story - they took a photo of Friedman with Cliff Montgomery and used Montgomery on the Friedman card by mistake.
