UNIQUE photograph film negatives MONGOLIAN MEN AUTOMOBILES CHINA MONGOLIA 1900s For Sale

Amazing unique antique photograph negative film of MONGOLIAN MEN & AUTOMOBILES IN MONGOLIA OR GOBI DESERT, CHINA; these images measure 3.75x6 inches each. The men wear traditional Chinese clothing; I think they are wealthy or important men who are being taught how to operate a motor vehicle by a Caucasian man; motorized vehicles were new to the region in the early 1900's.
BEST BET/MOST LIKELY - these show the introduction of the first auto to Mongolia. The info I found that suggested this is as follows:
The First Import (1920): The first automobile brought to Mongolia was imported around 1920 by a local merchant and later found its way into the capital, Urga (now Ulaanbaatar); there it was sold to Tsetseg Shagdar, one of the country's wealthiest merchants at the time.The Second Car (Royal Gift): Shortly after, a visiting foreign scientist or geographer brought a second vehicle into the country and gifted it to the ruler of Mongolia, the Bogd Khan.And the result: in 1921, Mongolia's earliest recorded car accident famously involved a collision between these exact two vehicles, the only two in all of Mongolia at the time.
THE FOLLOWING STATEMENTS ARE GOOGLE AI RESPONSES TO EACH IMAGE; they are for context only, but offer some historical and geographical details that seem to support this idea:
an early 20th-century vintage automobile, likely a Ford model delivered to Urga (now Ulaanbaatar) Mongolia around 1912 for the 8th Bogd Khan; man in traditional Mongolian attire alongside the vehicle.
Three individuals dressed in traditional layered robes and hats characteristic of early 1900s Mongolian attire; early use of motor cars replacing traditional camel caravans during scientific and trading journeys across the Gobi Desert.
