Putting a list together to make things easier, btw is this thread spoiler tagged? B/c it certainly should be, I'll hide the list below regardless. Not counting some of the stuff mentioned earlier like the Cap cards as they're a bit of a stretch for an easter egg, but I'm including the mid-credit one as it's a cool cameo.
I'm watching it again on May 3 midnight screening so I want a list to check off
Though by the length and popularity of this thread it looks like it's going to be a really short list relative to other MCU films.
