Nancy Columbia, best known as "Miss Columbia," was an Inuit from Labrador who was named "Queen of the Pay Streak" at the Alaska Yukon Pacific Exposition, the 1909 World's Fair held in Seattle. She is visible in the center of the image, between the two cables leading up and left. See Image 193 (193 - Miss Columbia at A.Y.P.E.) for another image of her.
Most of Otto's images of the A.Y.P.E. were in the 200 range, but some like this one are numbered in the 600s.
