The record that Holden buys for his little sister, Phoebe, is titled "Little Shirley Beans." The record is a symbol for innocence, particularly pertaining to one's childhood. Shortly after purchasing the record, Holden drops it in the park and it shatters, representing one of the novel's themes of innocence being lost in the "real world." After dropping it, Holden scrambles to pick of the broken pieces because even though the "innocence" is permanently shattered, he is desperate to gather any small form of it he can find. The fictitious record was supposedly sung by the real life 30's singer, Estelle Fletcher.
