Besides Captain America’s cameo and Stark’s presence, there are a few others. In Peter’s chemistry class, there’s a series of photos of famous scientists – Banner is up there. As well, there’s a mural of Howard Stark in the hallway.

Next door to Thai place where Peter and Aunt May eat, is a church called “Korean Church of Asgard.”

Finally, on the cargo ship transporting Stark’s stuff from the Avengers Tower, you can see a new shield for Captain America and Ultron’s head.
