The Alan Wood Steel Company was a small, family-controlled integrated steel company. The Upper Merion & Plymouth Railroad connected all the elements of the Wood steel-making complex. The collection includes three blueprint maps showing the layout of industrial buildings at Alan Wood Steel Company and the track of the Upper Merion and Plymouth Railroad Company. Also in the collection is a stereograph featuring a blast furnace plant in Pittsburgh, Pennsylvania.

The Keystone View Company was a major distributor of stereographic images. The company was founded by amateur photographer, B. L. (Benjamin Lloyd) Singley (1864-1938) in Meadville, Pennsylvania, in 1892. There are two stereographs in this collection, the first card shows "The Most Costly Docks in the Western Hemisphere, Buenos Aires, Argentina" and the second shows "Market Scene in Berkovitza, Bulgaria."
