Groot was created by Jack Kirby and Stan Lee, but I know you know that.
And this is a pretty cool new poster, gotta say:
And because it is Monday so I missed these earlier, here are two more posters for GotG characters who are not as cool as Groot, but still pretty cool.
Gamora was created by Jim Starlin, and you definitely know that too.
And Rocket Raccoon was created by Bill Mantlo and Keith Giffen, with a little bit of inspiration from the Beatles. And maybe you didn’t know that last bit.
