An official menu for a state banquet that bears the signature of former Chinese leader Mao Zedong has been auctioned for $275,000.
Boston-based RR Auction said the menu auctioned Wednesday was for a banquet held in Beijing on October 19, 1956, and commemorated the first state visit to China by Pakistan's Prime Minister Huseyn Shaheed Suhrawardy.
The menu was signed in fountain pen by six influential Chinese statesmen, including Mao and Premier Zhou Enlai. The banquet featured foods from both nations and included delicacies such as “Consommé of Swallow Nest and White Agaric,” “Shark’s Fin in Brown Sauce,” and “Roast Peking Duck.”
“To hold a menu signed by Mao Zedong and Zhou Enlai is to hold a piece of the past – a piece that tells a story of diplomatic engagement, cultural exchange, and the forging of friendships that have endured through the decades,” Bobby Livingston, executive vice president at RR Auction, said in a statement.
Other items auctioned off included a fully operational World War II-era Enigma coding machine for $206,253, a Thomas Edison-signed document for a light bulb patent for $22,154, and a check signed by Steve Jobs to Radio Shack was sold for $46,063.

The King Abdullah University of Science and Technology (KAUST) has been developing a new robotic system designed to automate date palm harvesting, SPA reported.
According to a KAUST press release, the system aims to revolutionize the agriculture industry and establish Saudi Arabia as a leader in agriculture innovation. The research, led by KAUST Assistant Professor Shinkyu Park, focuses on automating key processes in date farming, such as harvesting, pollination, and tree maintenance through AI-powered robotics, and promises to yield larger quantities of more nutritious dates.
Park's "robotic farmers" solution combines robotics for reliable farming and AI for greater efficiency. The robotic arms of the system will be able to move as quickly as a human farmer while precisely picking each date without damage to itself or the fruit. Equipped with high-precision visual sensors, the robotic farmers can identify individual dates, flowers, and tree structures to perform tasks such as harvesting, spraying, and pruning, ensuring tree health, productivity, and longevity while reducing the risk of pest infestations and diseases.
Field trials are scheduled to begin during the 2025 harvest season, with full operational capability expected within three years. Park suggested that a Robots-as-a-Service (RaaS) model could allow smaller farmers to access the technology without the burden of purchasing the robots outright.
The project is one of many at KAUST that will benefit date farming and food security. Such projects provide Saudi Arabia an advantage not only in agricultural technology but also in agricultural expertise, as leaders in farming and robotics are drawn to the region, while laborers will be the first to engage with the new technologies developed by Park and his team, according to the release.
"I am excited that this initiative extends beyond engineering solutions and cultivates research and development opportunities for local talent, contributing to the long-term sustainable educational and economic growth of the Kingdom," he said.
