This Looney Tunes t-shirt features a distressed image of Daffy Duck, the hilarious character who always let his rivals know, "You're despicable!" Daffy Duck first appeared on April 17, 1937 in "Porky's Duck Hunt" as an assertive, completely unrestrained, combative character, the likes of which audiences had never seen before. Daffy instantly became a classic cartoon character, and there was no looking back, as Daffy is still regarded as one of the all-time great Looney Tunes characters.
