​Rare: IPP29 San Francisco (2009) Official Souvenir Book

From the Private Collection of the late Bill Darah

​This is an exceptional opportunity to own the Official Records of the 29th International Puzzle Party (IPP29) held in San Francisco, California. These yearbooks are produced in strictly limited quantities—only for the ~400 invited attendees—and are virtually never seen on the open market.

​Elite Provenance

​This specific copy was a part of the personal library of the late Bill Darah, a legendary figure in the mechanical puzzle world. Bill was known for his impeccable taste and the meticulous care he took of his collection. This is not just a book; it is a piece of community history with a direct link to one of its greatest stewards.

​Condition: Pristine

​The book is in superb, collector-grade condition:

• ​Cover: The iconic orange "tie-dye" cover is vibrant with no fading, creases, or shelf wear.
• ​Binding: The spine is tight and perfectly intact.
• ​Pages: Crisp, white, and clean. No markings, highlights, or dog-ears.

​Inside IPP29

​The San Francisco party was famous for its fusion of puzzles and technology. This record includes:

• ​The Design Competition: Photos and details of the year's most innovative new designs.
• ​The Edward Hordern Puzzle Exchange: A visual catalog of every puzzle exchanged—an invaluable identification guide for collectors.
• ​Keynote Highlights: Coverage of the visit to the Babbage Difference Engine No. 2 and lectures by computer science icon Don Knuth.
• ​Event Records: Details on the Golden Gate Bridge walk and the "Puzzles as Art" exhibit.

​A Note on the Puzzle Community

​To maintain the spirit of the International Puzzle Party and show respect to the designers, I have intentionally excluded photos of the internal solution pages. These pages contain proprietary solutions that are part of the value of the book, and I believe it is only right that they remain a "secret" for the winning bidder.
