Philadelphia, Lippincott, (1958). A fascinating time capsule, written at the dawn of nuclear power and of air travel for the masses. Hogner covers water and land management issues, and loss of species, among other topics. Inscribed by the author and by her husband Nils Hogner, the illustrator, to Sherman Knapp, with appreciation for his assistance. Knapp, president of Connecticut Light and Power, is listed in the acknowledgments, and his title likely explains Nils Hogner's added illustration of a power line with his inscription. Bit of foxing to the hinges and joints; near fine in a very good, spine-tanned dust jacket with shallow chipping at the crown. [#036495] SOLD
