A Harlem faded ad keeps 1970s radio alive

The 1970s Top-40 music scene lives on thanks to this almost perfectly preserved ad, on the side of a building at 145th Street and St. Nicholas Avenue.

I’m guessing it went up in the disco era, when radios all across the metro area were set to 77 AM, then a hugely popular station.

WABC is all talk today—it’s been that way since 1982.
