Every 43 Seconds...
These crafty images were made by Jung von Matt for an advertising campaign for Gesellschaft für bedrohte Völker. The message is a strong one— every 43 seconds someone dies from gun violence. The grenade may be the only slightly out of place image among the other guns, but violence is violence, and these images are a skillful representation of it's consequences.
Correction: These images were originally created by artist, Francois Robert for his Stop the Violence series. The independent advertising agency, Jung von Matt (Jvm), created the advertising campaign. Thanks to Jamie for giving the correct credit.
