Great for Back to School! "Teachers Leave Those Kids Alone." This Pink Floyd T-shirt features one of the most enduring images in Rock & Roll history the album artwork from The Wall. Pink Floyd has always been at the vanguard of Concept Rock, and The Wall is seen by many as the quintessential embodiment of the genre. A cautionary tale, Roger Waters painted a picture of isolation and despair, the residual effects of his own childhood and the trappings of fortune and fame. The results were stunning, as the album has sold well over 50 million copies.
