This image shows the gift shop and likely reception desk for the Richardson’s Cabins, located just outside Yellowstone National Park in Montana.
The caption states:
RICHARDSON’S CURIOS AND CABINS
COOKE CITY, MONTANA
Indian Jewelry, Montana Moss Agate, On U.S. Highway 12, near northeastern entrance to Yellowstone National Park.
— Cook City is better understood to be a village or settlement, even today, as the population is only a few hundred and the locale is not incorporated as a town or city.
This card likely dates from the 1950s.
