What did John Candy's character sell in the American movie "Planes, Trains, & Automobiles"?

"Planes, Trains and Automobiles" is a 1987 American comedy film written, produced and directed by John Hughes. The film stars Steve Martin as Neal Page, a high-strung marketing executive, who meets Del Griffith, played by John Candy, an eternally optimistic, outgoing, overly talkative, and clumsy shower curtain ring salesman. They share a three-day odyssey of misadventures trying to get Neal home to Chicago from New York City in time for Thanksgiving with his family.

While some reviewers were critical of the gushy tones and silliness seen in the movie, which affected the ability to convey emotional range, most applauded the humor itself. Leonard Maltin called the movie a "bittersweet farce," adding that Hughes "refuses to make either one (Martin or Candy) a caricature—which keeps this amiable film teetering between slapstick shenanigans and compassionate comedy." Maltin added that the movie was "hurt by an awful music score."

The movie opened in American theaters on November 25, 1987 (a Wednesday) and finished third for the weekend, grossing $7,009,482. After its first five days, the film grossed $10,131,242 and stayed in the top ten for seven weeks. The movie finished its American run on January 22, 1988 with $49,530,280 after a twelve-week run on a production budget of almost $30 million.
