I posted a little about the old Sioux Trading Post earlier and got to do a little of my own research about the history. Here's a bit I found on the Ogallala, Nebraska store, not to be confused with the Sioux Trading Post in Rapid City, South Dakota (a native craft supply & dealer, which incidentally I've been to before) as well as some other facts about the colorful family-run operation:
In all three souvenir stores "Out West" have been owned by the Henline family over the years along the old Lincoln Highway. The Buffalo Bill Trading Post was on the west end of North Platte on Hwy 30, and was opened for business in 1950 and sold in 1954. The Sioux Trading Post (above) was in Ogallala, Nebraska, also on Hwy 30, was opened in 1952 and closed permantly in 1969. Fort Cody Trading Post of North Platte was first opened on Hwy 30 from 1963-1969 then relocated to be close to the new Interstate I-80 in 1968 where it continues to operate to this day.
First the Sioux Trading Post and later the Fort Cody Trading Post were the summer homes for the Whitecalf family of Pine Ridge South Dakota. (some members pictured above) The family lived in the back towers (at Ft. Cody) and performed their Native American Dances during the day for our customers. They also presented a half hour evening performance which featured traditional dances including the Hoop Dance. Their final summer in North Platte was in 1977, when they returned to live year 'round in South Dakota.
The Henline family also operated the Wigwam in Atlanta, Nebraska, and the Seminole Trading Post and Indian Village near Miami. They also ran the Dunlap-Henline Company that published postcards out of Omaha during the 1950's through 60's.
