From the first edition of Johnston's scarce The Physical Atlas..., these two matching maps together describe the geology of Great Britain. The first map is the northern sheet which carries the full title in a panel with engraved vignettes of skeletons, fossils, and the head of a Saber-toothed Tiger. The lower sheet contains the legend which identifies an amazing 25 different geological types. To the sides of the legend are numerous fossil Ammonites. Both sheets are filled with notations and tables. The maps are from the Sketches and Notes of Professor Edward Forbes, F.R.S., President of the Royal Geological Society. Surrounded by a keyboard-style border.

Vivid color on sturdy sheets with faint offsetting and a hint of toning along sheet edges. The bluish hue visible along the centerfold is caused by our scanner, and is not on the physical map.
