is that the building's topping out circa late 1969? Anyone remember the cartoon, Muppet Babies? There's a 1986 episode, "The Weirdo Zone," and near the beginning is footage of this building under construction.
Here's the link to that clip on youtube. The reference begins at about one minute. and runs for about 20 seconds. Toward the end of that roughly 20-second clip, you can make out the top of the Gulf Tower off to the left!
