More Marvel Easter eggs have been spotted in Sony's upcoming Spider-Man game for the Playstation 4. Promotional artwork for the game includes references to Iron Man, the Avengers Mansion, Black Cat, and more.

At E3, Sony revealed a new trailer for Spider-Man which shows off several characters from Spider-Man's rogues' gallery. In the video, Spider-Man battles the Scorpion, Rhino, Electro, and the Vulture. These villains join a list of numerous iconic Spider-Man characters who we know will have a presence in the game, such as Miles Morales, Mary Jane Watson, Norman Osborn, the Shocker, Mister Negative, and Kingpin. Considering how many Marvel characters have already been featured in trailers for the game, there's a lot of speculation on who else may make an appearance.

Outside the LA Convention Center's West and South Halls, was a Daily Bugle newsstand with promotional material for Spider-Man. E3 attendees were able to read free Daily Bugle newspapers. The newspapers are filled with easter eggs and hidden references to Marvel characters that extend beyond the world of Spider-Man. Daredevil is also mentioned.

One Easter egg in particular was a real estate ad for a 19th century home with the address of 890 5th Avenue. In the comic books, the address is the location for the Avengers Mansion, the original headquarters for Earth's Mightiest Heroes. According to the ad, the mansion belongs to a "prolific NYC industrialist", which is clearly a reference to Iron Man's alter ego, Tony Stark. In the source material, Avengers Mansion was owned by Stark and managed by his personal butler, Edwin Jarvis.

One of the articles in the newspaper—written by Peter Parker's first comic book girlfriend, Betty Brant—details a string of robberies where all the victims are the city's most wealthiest families. Next to the article is an image of a black cat figure. Spider-Man fans will be able to note that the culprit is Felicia Hardy AKA Black Cat, who is already set to appear in DLC for the game.

Though the Avengers Mansion and Iron Man reference may be nothing more than Easter eggs, the article about the Black Cat may actually have significant importance to the plot. This, and other articles featured in the paper, may hint at certain events that take place in the game's story. Spider-Man continues to find ways to connect to various Marvel properties. Now we know that Iron Man and the Avengers exist in Spider-Man's world, which also includes Black Panther and Doctor Strange. It remains to be see if Spider-Man will set the stage for a shared universe of Marvel games.
