"[Lot of 2] Geological & Paleontological Map of the British Islands [and] Paleontological Map of the British Islands", Johnston, Keith

These are actually matching maps that 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 formations with hand coloring and engraved texture. 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 keyboard-style border. Blank verso.
