The play "Picnic" was written by William Inge. It was produced and published in 1953 and won the Pulitzer Prize for Drama that same year. The play explores small-town life and complex human relationships in 1950s America and has been highly regarded for its depth and portrayal of darker themes beneath its surface story.
Additionally, the novel "Roadside Picnic," a different work, was written by the Soviet authors Arkady and Boris Strugatsky in 1971, but the play "Picnic" specifically refers to William Inge's work.
