Animal On T-shirt

Beginning in the late 1960s, the T-shirt became a medium for wearable art. Psychedelic art poster designer Warren Dayton pioneered several political, protest, and pop-culture art T-shirts featuring images of Cesar Chavez, political cartoons, and other cultural icons in an article in the Los Angeles Times magazine in late 1969. Today, many notable and memorable T-shirts produced in the 1970s have now become ensconced in pop culture.
Examples include the bright yellow happy face T-shirts, The Rolling Stones tops with their "tongue and lips" logo, and the iconic "I ♥ N Y”.
Another popular shirt design among tourists is the funny phrase, “My parents went to ______ (name of place), and all I got was this lousy shirt!”.
They can also be used to carry commercial advertising, souvenir messages, and protest art messages.
