The Presko Binocular Company of Chicago was one of the later stereoview producers. They issued their views during the period 1910-1920. There is no evidence that this publisher ever produced any original views, instead they bought negatives from prominent photographers of the day. Their subject matter was confined to varied United States scenery with numbers into the #500’s. Locales included Florida, Oklahoma, Colorado and Canada. The views are somewhat uncommon (probably a low print run) and are on curved, gray mounts.

All Yellowstone stereoviews produced by Presko all appear to be re-issues of other photographers. Most appear to be by T. W. Ingersoll, with a few by others. The numbering on the obverse of the views is unchanged from their original styles. So although it may appear, based on the numbering, that Presko may have issued boxed sets, they in fact were only reproducing the original photographers numbering system on any given view.
