Unmatched Pair of Antique Physiography Notebooks with Many Diagrams (and Useful Info!) carved hummingbird 625ʺ diameter × 2I purchased these two separately, but with the marble covered one filled just a portion of the way through (lots of blank pages to put to use now should one wish), I thought they'd be good to offer as a pair. Both are notebooks for Physiography classes covering processes and patterns in the natural environment such as the atmosphere, hydrosphere, biosphere, and geosphere. (Facts!) Of course I'm always a sucker for the hand drawn diagrams in notebooks
