Antique Kansas and South Dakota Map Circa 1880-1890

Old map of South Dakota with a map of Kansas on the reverse.
It is 10 1/2" x 13 1/2" and produced between 1880-1890.
The maps show cities, counties, rivers, mountains, railroads lines and other topographical marks of that time period.
The Kansas map states public lands/Indian Territory along the bottom.
The edges of the map have darkened and are brittle with some small tears along the edge.
There is writing in pencil from the prior owner along the edge of the S.Dakota side that states Kansas on back and there are some stains along the bottom edge.
No publisher information.
It looks like the map was part of a map book.
