Pennsylvania Beautiful by Wallace Nutting

Pennsylvania Beautiful is a 1924 pictorial book by the American photographer and antiquarian Wallace Nutting, part of his "States Beautiful" series.  It is a heavily illustrated tribute to the eastern half of the Keystone State, featuring black-and-white photographs and drawings of landscapes, old houses, winding rivers, and rolling hills across the counties Nutting describes. 

First published in 1924 by the Old America Company; later reissued by Garden City Publishing (1935) and Bonanza Books (1954), with modern facsimile reprints since.
Around 296–306 pages, illustrated throughout by Nutting himself.
A regional-Americana classic, valued by collectors of early American photography and historic architecture.
