Railways of the Twenthieth Century, VGUC

Train and history lovers! It's a hardcover of Railways of the Twentieth Century, by Geoffrey Freeman Allen. Covers railroad history and technology (rural and urban, mostly American and European) of the Twentieth Century until it's 1990 publication.  Has many (mostly black and white) photos, some informational illustrations, and each chapter begins with a large and beautiful illustration of a specific model of train.  As shown in photos, it has a tear to the slipcover and minor damage to the book exterior. Otherwise very good condition, so overall Very Good Used Condition!
