The legendary Professor STEPHEN HAWKING. Autograph - his official stamped signature - on First Day Cover from "Einstein to Stephen Hawking". Have never seen another one like this.As Hawking could not write, he authorized on very rare occasions that a stamp of his autograph was used by his Cambridge office. This is one of the rare items with the stamped signature. The only signed First Day Cover of him that I have ever seen -- probably unique!! And probably the best association possible: the two geniuses of the 20th century - Einstein and Hawking.
