parts 1 thru 23 of the 1892 RAND MCNALLY & CO ENCYLOPEDIA AND GAZETTEER with colored maps and illustrations. Every section I looked to had 4 pages of color full page atlas maps in the back. I have shown a few examples. I am not sure if this is a complete set but it is complete from sections 1 thru 23. Nice shape. Edges of pages have some minor fraying.
