Edmund V. Gillon/Museum of the City of New York
Gillon has published more than a dozen books on New York City, the museum notes.
Some of the city's landscape looks the same today as it did back then, but some areas look drastically different.
Today's downtown skyline is missing the Twin Towers, and Times Square has transformed dramatically since the '70s with the addition of many more lit-up billboards and signs.
We've published a selection of Gillon's photos with permission from the museum.
