The three posters are captioned “Quickest way to get home,” “Straight A superhero,” and “Homework can wait, New York can’t.” The trailer offers a brief glimpse at the tech Spidey will use, probably given to him by his friend Tony Stark.
Spider-Man: Homecoming releases in theaters on July 7 (see "Best in Shows--Q3 2017").
The first trailers can be seen here: see ”First Official 'Spider-Man: Homecoming' Trailers.”
