This is a commemorative silver spoon, a novelty item from the 11th Tokyo Motor Show held at the Harumi Exhibition Hall in 1964 (September 26 - October 9, 1964). The 11th Tokyo Motor Show marked a historic turning point, as it was renamed from the "All Japan Motor Show" of the previous year to the "Tokyo Motor Show," and overseas manufacturers began to exhibit, marking the beginning of its journey as an international motor show. This is one item from the collection of my father, who was involved at the time. The hallmark on the back reads EPNS (Electro Plated Nickel Silver), indicating that the base is an alloy (copper, zinc, nickel) with a silver plating on the surface. The central logo is the symbol mark of the motor show at the time, designed with motifs of a car wheel and steering wheel. It also features the SSKK Sato Shoji symbol mark, "Martian of Martian." 1964 was also the year the Tokyo Olympics were held, and this 11th Motor Show was a crucial turning point for Japan's automotive industry, with prototypes of the Toyota Corolla and Nissan Sunny, which would later symbolize Japanese motorization, being exhibited. The box is not included. There are minor scuffs due to age. It has been cleaned and is now in good condition. It is a cherished item, and I would be most happy if it could be passed on to someone who will continue to treasure it. If used as a sugar spoon, it will exude a full Showa-era atmosphere.
