But he also captured the seemingly ordinary street scenes that offer fleeting glimpses into the heart and soul of the late 1970s city: shoppers going in and out of mom and pop stores, musicians and vendors drawing crowds, and taxis navigating traffic-choked streets.

Thirty-eight years later, van Wijk decided to share his previously unseen images, and Ephemeral New York has the wonderful privilege of posting them.

It goes without saying that the Gotham of 1979 was a vastly different place. These days, everyone wants to live in New York; in the 1970s, residents couldn’t get out fast enough. The city’s population dipped an incredible 10 percent from 1970 to 1980, to just over 7 million.

Ed Koch had been elected mayor a year earlier on a law and order platform. The city’s nickname, Fear City (or more ironically, Fun City), was a nod to rising crime and rampant graffiti.

Cuts in city services left garbage on the streets, and shells of buildings sat empty in the South Bronx, East Village, and the Lower East Side, among other neighborhoods.

You wouldn’t know any of this from looking at these photos. The city in this collection of images is animated and colorful, with life and energy.

It’s a New York that feels almost small scale compared to the contemporary city—more a collection of neighborhoods rather than an island of cookie-cutter stores and development.

The gritty, street-smart New York of the 1970s is often hailed as a more authentic version of the city. How true that is has been up for debate lately.

These photos don’t take a side. They’re simply fascinating portals into the past that bring memories back of the city in the late 1970s, before crowded subways, a critical mass of Starbucks and Duane Reade stores, and an army of residents wearing white earbuds as they go about their day.
