Vintage fountain pen signature, “With my best wishes for a wonderful future, Lee de Forest, March 11, ‘39,” on a 5.5 x 2.75 blue card from the Albert R. Chestnut collection. In fine condition, with a small photo attached to the left blank area. From his Pennsylvania home, Chestnut, a printer by profession, began collecting autographs in 1935. He sent these personally-printed cards to over a thousand celebrities and received favorable replies from the vast majority, finally retiring from collecting to raise his family when postage increased from 2¢ per card!
