The upcoming Julien's Auctions event, titled 'Kaiju King: The Sompote Sands Legacy Collection,' marks the first time these personal archives have been made available to the public. Amassed over five decades, the items were previously housed at 'Sompote House,' the director's private museum in Thailand. The sale coincides with the 60th anniversary of the Ultraman franchise, honoring a career that bridged Southeast Asian storytelling with Japanese practical effects.

Highlights include an original Ultraseven production mask from 'Hanuman and the Seven Ultramen,' estimated at $5,000 to $7,000, and a rare 3D painting of Ultraman signed by legendary character designer Tohl Narita, valued at up to $20,000. Beyond the monster suits and miniatures, the archive features personal artifacts from Sands' early career in Japan, such as his annotated script and 35mm camera used on the set of the 1962 classic 'King Kong vs. Godzilla.' Collectors can participate in the live event at Julien's Studios in Gardena, California, or via online bidding platforms.
