The image shows a technical drawing related to railway engineering, specifically titled "Boston Elevated Railway - Types of Bolted Frogs", dated December 10, 1903. It appears to be plans for components of elevated subway construction for the Boston Elevated Railway.

The drawing includes detailed schematics and outlines for four different types of rail frogs, labeled as Type D, Type C, Type A, and Type B. These are components used in railroad tracks to enable the trains to switch from one track to another. Notes and specifications are written alongside the diagrams, and some mention gauge details or design characteristics.

The blueprint is taped down at four corners on a board to hold it in place (likely for photographic documentation or study). The image appears to be a black-and-white photo negative, which is why the text and plans appear inverted, and the tape is visible as thick dark strips securing the drawing.

It is an artifact of historical engineering showcasing early 20th-century design practices for rail infrastructure.
