It's the veritable motherlode of humorous pop culture-themed Zelda shirts.
The guy behind all the art is illustrator Blair J. Campbell. He came up with something called "Octoroktober", challenging himself to do one Legend of Zelda-inspired shirt design on each day in the month of October. The results are pretty awesome.

There's also this riff on Dawn of the Dead:
Zelda as Ziggy Stardust:
A Zelda version of Three Wolf Moon:
A variation on the famous "We Can Do It!" WWII propaganda poster:
And Ganon as Porky Pig:
Make sure to check out the rest of Campbell's work at his TeePublic shop, and all 31 Zelda designs in the embedded imgur album below. Octoroktober - 31 shirt designs for each day of this past October. [r/zelda]
