I originally found these on reddit. I’m not exactly sure which sub-reddit, but it was of Iron Man, Hulk, Thor and Captain America all together. I thought it would look better if they were separate So I started with the Hulk. As far as who the original creator was… I’m not sure exactly. The best I can do is this etsy store I believe. If I’m wrong let me know and I’ll give proper credit. Enjoy!
