This is a hardbound edition of Christian Science by Mark Twain, signed by Twain on the interior front cover. Twain has signed his name in black fountain pen upon an affixed bookplate of a former owner. Mark Twain was the pen name of Samuel Langhorne Clemens (1835-1910), famed American writer, humorist, and essayist. Since this book was published in 1907, it was signed by Twain just shortly before his death on April 21, 1910. The 362-page book displays light wear to the boards, with slight separation along the spine. A typed name label from a different owner is affixed to one of the interior pages. Excellent condition overall.
 
This comes with a full LOA from PSA.
