The Mitchell family started to produce atlases in 1846, and continued into the early 1890s. Around 1860, S. Augustus Mitchell Jr. took over, and the atlas would be called Mitchell's New General Atlas. This is very colorful version of the Iowa and Missouri map from the 1869 installment of this atlas.
