That's some firepower.
Artwork by Art Spiegelman.
Spiegelman said this recently about the cover on his Facebook page:
I did this New Yorker cover in 1993. Colombine happened in 1999, Newtown in 2012, nearly 20 years later. My wish for 2013: let Newtown be remembered as the turning point—I'm hoping that kids with guns can become ironic again.
Thanks to Dangerous Minds for remembering this issue.
