A brief overview of this week's auction offerings:
Sotheby's London will sell Important Manuscripts, Continental Books and Music, in 231 lots on Tuesday, June 11. Rating the top estimate by a fair margin is a calligraphic autograph letter written by Mao Zedong to the journalist and family friend Yang Yi, at £300,000–400,000. The auction house reports that this is the only known Mao autograph letter ever sold on the international market. A first edition of Descartes' Discours de la methode pour bien conduire sa raison (1637), once owned by the natural philosopher Thomas Henshaw, is estimated at £50,000–70,000. A collection of manuscript quotations and tributes to David J. Bach, being sold on behalf of the Master and Fellows of Gonville & Caius College Cambridge, could fetch £40,000–60,000.
On Wednesday, June 12, Christie's New York will hold a single-item sale at 2 p.m., a first edition of Luca Pacioli's Summa di arithmetica (Venice, 1494), very rare in complete condition and in an original binding. Containing the first published description of double-entry bookkeeping, this book is considered a major influence on modern economics, and is estimated at $1–1.5 million.
Immediately following the sale of the Pacioli volume Christie's will sell 232 lots of Fine Printed Books & Manuscripts Including Americana. A galley proof of Watson & Crick's Nature article "Molecular structure of nucleic acids: A structure for deoxyribose nucleic acid," signed by both authors, is estimated at $180,000–250,000. Another Watson & Crick galley, also signed by both authors, could fetch $120,000–180,000. A 1794 George Washington manuscript letter to the governor of Pennsylvania about the Whiskey Rebellion is estimated at $100,000–150,000. Other highlights may include Poe's pocket watch ($80,000–120,000); several letters from Benjamin Franklin to Lord Kames (Lots 103–110), and a 1776 Jefferson letter to his friend John Page ($50,000–70,000).
Finally, on Thursday, June 13, Bonhams New York will sell Fine Books and Manuscripts, in 307 lots.

A first printing of Shakespeare's Coriolanus, extracted from the First Folio, could sell for $40,000–60,000. An 1869 Darwin letter about arranging for a second American edition of Origin is estimated at $20,000–30,000. A first edition of Swift's Gulliver's Travels could fetch $15,000–25,000.
