London: W & A.K. Johnston. A map of Asia, extracted from the General Atlas. This conforms best to the 1879 edition, except the lack of page title to the top edge, and the different page number. Engraved area is 13" x 17" (sheet is 14^1/2" x 18^1/2"). Lightly tipped onto mounting board, and now protected by archival protection. A lovely copy of this map from the height of colonial era.
