That poster is one of (albeit the most creepy and sexist) a group of parody posters made by fans of the MCU. Other such fan posters include this equally abhorrent creation:
And my personal favorite:
The only official posters released by Marvel are the ones depicting Iron Man, Captain America, and Thor.
There’s a post rolling around attempting to blame Marvel Entertainment for the fan-made posters, calling them sexist and worse. Marvel does have trouble with representation in their works, but even they wouldn’t make a mistake this large. Spread the word!
