Almost impossible to find autographed 3.25 x 5.5-inch sepia-tone postcard portrait-- although signatures and letters abound-- neatly signed along the bottom border in black fountain pen around 1908-1910, further desirable in that he wrote his full name, and not just A.C. Doyle or Arthur C. Doyle. Around the year this card was signed, he was penning classic Sherlock Holmes stories like "The Adventure of the Bruce-Partington Plans," "The Adventure of the Dying Detective," "The Disappearance of Lady Frances Carfax," "The Adventure of the Devil's Foot," and "His Last Bow." Another example of the same image sold at auction in 2012 for $1,986.00; this one is priced to reflect light edge wear; a very minute crease to the lower right-hand corner; markedly heavy silvering, which is not so bad when the photo is viewed head-on; and a touch of show-through from the word "Post Card" printed on the back of the card. Beloved Scottish physician and author Sir Arthur Conan Doyle is remembered as the creator of Sherlock Holmes, arguably the greatest gumshoe in the history of crime fiction, as well as for his Professor Challenger sci-fi series and the fantasy novel The Lost World.
