This is from the Baltimore and Ohio RR with fantastic map "Into the Heart of New York City" showing B&O Motor Coaches, I.R.T Subway ... B.M.T. Subway ... Elevated Lines ... Hudson Tubes ... Bridges ... all the shipping piers  etc. along the Hudson and East Rivers. Map covers from Brooklyn to Battery Crossings up to 65th St and Central Park. It folds out to a nice 13" x 21" size. Map dated 9/1926 by Rand McNally. Front cover has November 28, 1926 date. There are some small tears in margin and a small piece missing in margin at bottom left between 8 and 9 grid numbers.  One small hole at Canal and Greene St, at 4 way fold intersection.

This is one of many maps from the collection of Robert B. Sosman I will be listing over the next several months. Robert Browning Sosman, 1881-1967, spent his early life after college doing experimental activity at the Geophysical Laboratory as a physicist and chemist. He was a pioneer in American ceramics and professor of ceramics at Rutgers University from 1947 to 1962. He spent a great deal of time after graduating college in 1903, traveling the U.S. and the world , analyzing soil compositions,

giving lectures, and whatever else was required of a physicist and chemist. He collected maps from everywhere. He had many related to transportation, subways, railways, streetcars etc.. Some were probably just for him to get around, with some related to his job. Living in Westfield, NJ, there are many from around that area, Bergen County and New York City. There are many scarce and unique Subway maps, as well as other maps. I acquired a large selection of his maps and ephemera at auction in Boonton in the early 2000's. I sold much of the travel brochures and ephemera a long time ago, but kept most of the maps. I'm ready to pass them on now.
