The first section of Ohio in Historic Postcards describes the rise of the picture postcard and its Golden Age and gives a sketch of turn-of-the-century Ohio, a burgeoning economic power. Section two is an album of postcards divided into ten sections: Ohio Landscapes, Commercial Structures, Public Buildings, Monuments and Memorials, Religion, Education, Transportation, Industry, Ohioans at Work, and Ohioans at Play. Each unit of postcards begins with an overview of Ohio's progress in the areas depicted on the cards. H. Roger Grant effectively illustrates the importance of the cards, both as artifacts and as images, and ties them to the story of Ohio.
