Recently Threadless challenged artists to illustrate “the battle between Spider-Man and his archnemesis.” Some of the winners, which appear on t-shirts in the company’s new Spider-Man collection, take “battle” literally (I particularly like Yannick Bouchard‘s Spider-Man vs Green Goblin), some are more metaphorical (Blair Sayer and Ross Zietz‘s Changes), and others take a more whimsical approach (Robert Thomas‘ Rock! Paper! Scissors! Web!?). A few of my favorite pieces are behind the jump; you can check out all of them over at Threadless.
