Extremely rare autographed limited edition (of just 5,000) first day cover, honoring a British set of Sherlock Holmes postage stamps, canceled at Grenada Studios in Manchester, England in October of 1993. Handsome Jeremy Brett famously portrayed Sherlock Holmes in the beloved Grenada Television series, flanked by Edward Hardwicke, who played his trusty Dr. Watson. In excellent condition and superb for display. Brett was also memorable as Freddy Eynsford-Hill in My Fair Lady (1964). He died of heart failure at the age of 61, after years of eluding fans and using secretaries to answer his fan mail, and this is an especially desirable, incontrovertibly authentic exemplar.
