This lot contains two plans of Chicago and surrounding region by the famous Warner & Beers firm, renowned for their state and county atlases. The first is dated 1875 (13.4 x 16.4") and is an early and very detailed post-fire map of the downtown region. The map extends to the Union Stock Yards and Brighton Trotting Park at Thirty Ninth Street in the south and up to Wrightwood Avenue and Fullerton Avenues in the north. The map shows and names all streets. Locates Central Park, Douglas Park, Union Park, Humboldt Park and Lincoln Park. The rail lines of several railroads are delineated and named. The large Government Pier and Light House are drawn at the Chicago River as it enters Lake Michigan. Surrounded by a finely engraved border with blank verso.

The second map is undated (14 x 16.5") but is from the same source so circa 1875 seems in order. This map provides a wider view of the area naming Deer Grove, Aurora, Joliet and extending south to include Wilmington with the counties of Reed and Wesley below. Each county is individually colored and all towns of any size are shown in grid block style. Excellent depiction of railroads, all named and most entering Chicago. The map also shows a complex network of Public Roads. A nice pair of maps.

Minor soiling in the blank margins along with a few tiny edge tears closed on verso with archival tape. The second map has a chip in the bottom right corner.
