In September of 1898, the Grand Army of the Republic, the G.A.R., held it's annual encampment in Northern Kentucky and Cincinnati.  You can read a lot more about what the GAR was about at this site.  The annual encampments were not unlike what today we would call conventions, and the beaches of Dayton were a big attraction of such gatherings.

For the GAR Encampment, the City of Dayton, on Saturday, September 3, 1898,  published a Souvenir Booklet.  It's around 100 pages, and it's chock full of pictures: people, social groups, houses, and commercial buildings.  It has biographies and histories, and it's ALL reproduced herein.  Hit the back button, & enjoy.
