The Sterro-Photo Company (rarely seen as Stereo-Photo) offered broad United States scenery starting in the mid 1890’s. Their views are uncommon, but numbers have been seen as high as #995. Their subject matter was different than that of major companies of the time. Most of their material was original, although a few were pirated. Among the topics they released were cats and dogs, hunting, flower shows and risqué views.

One of their rare Yellowstone views is shown below.
