A first edition signed copy of Mark Twain's Innocents Abroad achieved $10,800 in PBA Galleries' Fine Literature auction in San Francisco on July 31.

The book, inscribed by Twain to his wife, Olivia - "To Livy L. Clemens, With the love of S.L. Clemens" - beat the estimate of $8,000 by 35%.

The book is one of only a handful of examples inscribed by Twain to his wife

It was published in 1869 and details the author's travels around the Mediterranean and into the Holy Land aboard the USS Quaker City.

He was introduced to Olivia by her brother Charles Langdon while aboard and married her the following year.

The lot is one of only two known copies inscribed to her that has come to auction in the past 30 years.

We have this pamphlet for the 1907 Jamestown Exposition, which has been signed by Twain.

A handwritten letter by the modernist author James Joyce made $5,700.

It dates to 1936 and relates to the mental health of his daughter, Lucia, who was institutionalised a year earlier after showing signs of schizophrenia.

It reads, in part: "At the present moment the general opinion of the doctors is that it is definitely not an incurable case and probably not now to any great extent even a mental case but one of acute nervous disequilibrium…

"In any case her transfer here was a psychological blunder which has to be undone. Sincerely yours, James Joyce."
