Here are two of the dozens of postcards sold at the 1909 Seattle World's Fair depicting members of various native populations from Alaska, Yukon, and regions up there. The official card from the exhibition identifies them as Eskimos. The term Eskimo refers to the indigenous people groups of far northern North America, but is widely viewed as offensive or inappropriate today. The term was imposed by non-Indigenous colonizers. The variation "Skimo: is likewise not encouraged today.
The second card taken near their "snow capped tent structure" is a strange mix also, with an assemblage of mariachi band players posing with the native group. The middle group in this card looks like they are from an Asian country, perhaps Tibet? Someone more knowledgeable might let us know here.
