This picture is of a one-room schoolhouse in Adams County, Ohio.  Adams County was established in 1799 and named for John Adams.  This was when Ohio was still part of the Northwest Territory even before it became a state in 1803.  So it was one of the original counties in Ohio.  It is the next county due south and east of Highland County, Ohio, where I grew up, and the seat of Adams County is West Union.  The county is situated on the Ohio River between Brown and Scioto Counties.  The photograph was evidently taken as part of a library project conducted by the Works Project Administration of Franklin D. Roosevelt's New Deal during the Great Depression.  Unfortunately, the exact name, location, and current status of the school were not included with the photograph.
