Visuals: On a black background, there is a large "13" with the letters "WNDT" below it on the left side. On the right side, we see the text "A PRODUCTION OF", and "EDUCATIONAL BROADCASTING CORPORATION NEW YORK" with "EBC" between them.

Technique: None.

Audio: The closing theme of the show.

Availability: Found on shows on the American Archive of Public Broadcasting.

2nd Logo (September 12, 1968-1971)
Visuals:
 * Opening: On a black background, a large ring made of dark red bars appear one-by-one. They brighten up to as a smaller ring made of dark green bars appear by the same effect and the large ring flashes to . An even smaller ring of bars appears in dark teal. The rings then fade through different colors for about three seconds as a  bar ring slides into view, along with "IN COLOR" below. The rings fade out and the text "PRODUCED IN NEW YORK BY WNDT" appear below in a white Futura font and stacked with each other. "IN COLOR" continues to slide along the bottom of the screen until it goes off screen.
 * Closing: On a black background, a winding path of yellow bars appear one by one, followed by a dark red path of bars behind it. They form 3 bar rings, which turn, , and yellow respectively, and eventually slide into each other to form a yellow ring. The yellow ring then turns into a // ring as the same text in the opening variant appears below, with a copyright reading "©1970 EBC" appearing below. The ring then "spins" through its colors before fading to dark green.

Variants:
 * A still variant exists of the closing variant.
 * On the Realities episode "Soldiers Who Search and Dissent", this is used as a still in-credit logo, in monochrome. "WNET" replaces "WNDT", and the copyright year is given as 1971.
 * A (.*) variant has the text replaced by "PRODUCED IN NEW YORK BY serif", with the callsign in a larger size, and the copyright for EBC has the name in full. The wheel also doesn't change colors as it cuts to the new end product, and the text zooms out into place.

Technique: Cel animation.

Audio: A funky bongo beat.

Audio Variants: On Soul!, an announcer will either say "Produced in New York by WNDT." or "Soul! was produced in New York by WNDT."

Availability:
 * This was used for only a short time before it merged with NET to create WNET (they would also use this logo very briefly).
 * It can be seen on the Shout! Factory TV print of the March 5, 1970 episode of Soul! (incorrectly stated to be the first episode of the series) and appears to have been used for the first three seasons thereof. It also appears early on in the documentary Mr. Soul!.
 * The in-credit version appeared on occasional episodes of Realities, including "Soldiers Who Search and Dissent".

Legacy: While not much was known about this logo's existence until very recently, Shout! Factory put up the original episodes on their Shout! Factory TV service. Also, the copyright on the bottom of the logo stands for Educational Broadcasting Corporation, the holding company for WNDT; the name existed until 2011, when it was renamed to WNET.org.
