1869. · Philadelphia:
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 an attractive colorful single page map of the states of Massachusetts, Connecticut, and Rhode Island from the 1869 installment of that atlas. Good detail, and Portland is featured in an inset.
