If you think Marvel and DC can't get along, artist Darren Rawlings of Thinkmore Studios and The Silver Six has something to say about that in his "Little Friends" series. Each image features characters from both companies coming together, like Black Cat and Catwoman chasing a ball of yarn, Sandman and Clayface building a castle together or, as seen above, Green Lantern and Quasar engaging in a friendly competition.
Of course, not everyone is getting along ...
Check out the rest of them, as well as a lot more art, at Rawlings' DeviantArt site or on his blog.
