And the most childish artwork is...attack on canada!

The world's longest unguarded border explodes in Austerlitz's artwork "attack on canada (terrorist haven)." These child-like scribbles are undeniably a pure art-form, depicting how insidious, unscrupulous, despicable Canadians are harboring terrorists, and how the free world (Team USA) is in the process of kicking their sorry maple-syrup-eating arses.

GiliusThunderhead also weighed in on the scene, depicting a nightmare scenario where the whole damned Pacific Northwest secedes and take sides with the Maples Leaves. The filthy rapscallions.

With a PA-G score of 9, this artwork was bumped to the top of the heap, earning it the title "Most Childish Artwork" in all of Paint Avant-Garde. Congratulations Austerlitz! But more importantly, this artwork highlights the grave danger our country faces from the scheming, conniving beaver-lovers right across our border. Time for more nation-building, anyone?
