I won't bore you with all of the history, as you can look it up for yourself if interested, but the addressee on that printed envelope to "The Nation" Magazine has a bit of history of its own and all of which fits with the 1885 postmark:

Excerpt from Wiki:
The Nation is the oldest continuously published weekly magazine in the United States. The periodical, devoted to politics and culture, is self-described as "the flagship of the left." Founded on July 6, 1865, it is published by The Nation Company, L.P., at 33 Irving Place, New York City.
In 1881, newspaperman-turned-railroad-baron Henry Villard acquired The Nation and converted it into a weekly literary supplement for his daily newspaper the New York Evening Post. The offices of the magazine were moved to the Evening Post's headquarters at 210 Broadway. The New York Evening Post would later morph into a tabloid; the New York Post was a left-leaning afternoon tabloid under owner Dorothy Schiff from 1939 to 1976 and, since then, has been a conservative tabloid owned by Rupert Murdoch, while The Nation became known for its left-liberal politics.
