Yesterday, fans were blown away by the latest trailer for "Spider-Man: Homecoming," which was jam-packed with new gadgets, a cameo from a certain First Avenger, and of course, plenty of Easter eggs. However, Alamo Drafthouse's Mike Sampson happened to spot a blink-and-you'll-miss-it reference to the first appearance of the film's primary antagonist -- the Vulture -- in quite the unexpected place.RELATED: Spider-Man: Homecoming is the First Look at the New Tony StarkIn the below still from the trailer, the focal point is clearly the web-slinger, as he delivers his unique brand of justice as only Spidey can. However, when you zoom in on the image, you can faintly make out a New York license plate that reads "SM2-0563." This would appear to refer to "Amazing Spider-Man" #2, aka the book in which the Vulture made his debut back in May, 1963.

Is this merely a coincidence, or was it a conscious decision made by someone behind the scenes? Well, a follow-up tweet from the director himself, Jon Watts, indicates that it's the latter.
