The Fantastic Four: First Steps begins in its own reality before sending its heroes into the MCU proper. And now, in that reality-bending tradition, a little bit of the Marvel Universe has become part of the real world, thanks to Manhattan renaming the corner of Essex St. and Delancey St. as Jack Kirby Way/Yancy St.
That exact corner marks the neighborhood where Fantastic Four co-creator Jack Kirby grew up, which in turn inspired the fictional Yancy St. in the Marvel Universe, the rough-and-tumble home of Ben Grimm, the Thing.
