Visitor's catalogue of the Museum of the Peabody Academy of Science, Salem, Mass. : with references to books in Salem libraries
A visitor's catalogue issued in 1879 by the Peabody Academy of Science in Salem, Massachusetts, for people touring its museum, with two printed floor plans of the galleries. The pages are rotated sideways, with dense labelled rooms, numbered cases, and walls drawn as heavy outlines; a designer might take the orderly grid of rooms and small numbers as a model for wayfinding diagrams or architectural schematics.
