John Lennon & Yoko Ono - Skate or Die

I'll be honest...I don't have a clue what this pic is about...sordclassic.com doesn't seems to exist, and I can't find this picture anywhere else on the net, with a description.
Meh, I like this pic and that's why I'm posting it (I don't really think that's a liable reason and I probably won't update this post with a better one)
