This image is typical of how they displayed relics back then - cram as many as they can in the area and overwhelm the public. The same a style of images can be seen from other fairs during the war as well as the post-war displays by people like Charles F. Gunther, who began collecting all sorts of items - most of which remain in the collections of the Chicago Historical Society.
The good news is that you can see how much stuff there was on display; the bad news is that you cannot tell very well what the items are in any detail.
