In the classic 1966 Michelangelo Antonioni film, "Blow-Up," the protagonist is at a small rock concert where pandemonium breaks out as the lead guitarist throws his guitar into the audience -- putting it up for grabs.
A fight ensues. Somehow, the protagonist ends up with the guitar and scoots into the street chased by an angry mob -- all demanding the instrument. Soon he looks back and the mob is gone. He looks at the guitar one last time, then throws it into the trash.
