These maps are from a large Rand McNally Atlas that was probably published around 1892.  (The Chicago map shows the future location of the Columbian Exposition.) Note that there is text on the other side of the map.  A photo of the text on the other side is shown. The maps are approximately 14.5 x 22 inches in size.  

The maps will be shipped in a strong cardboard tube that is 3 inches by 25 inches.  White plastic inserts cap each end of the tube. (See photo of the cardboard tube.)

The cardboard tube should hold more than one map reducing shipping costs.
