Looking skyward and the earth, illustrated
An amateur astronomy treatise by Isaac Newton Snyder, printed locally by the Express Printing Co. in Liberty, Indiana, in 1911 for general readers curious about the heavens and the earth. The single plate is a dark, heavily grained halftone of a receding arched tunnel with concentric rings of light closing around a black central shaft, useful as a ready-made vignette of depth, eclipse-like rings, or coarse photographic grain.
