Marvel's Stan Lee congratulated Marvel Studios for their 10th anniversary...
...But he also made fun of them a little bit.
10 years ago, the Marvel Cinematic Universe began with Iron Man.
A special 10 year logo was revealed at the 2017 D23 expo, along with a class photo.
So Stan Lee went to Instagram to say ?Congratulations...I?ve been in the business for 77 years ? only 67 more to go and you?ll catch up to me!?
