Launching a 12-speech day which carried him through southern Illinois and on to Springfield, Senator John F. Kennedy campaigned vigorously Monday on the East Side after an overnight stop in St. Louis. At Granite City (above left), he met one of the day's biggest turnouts, an estimated 3000 persons who gathered in the Bellemore Village Shopping Center. Another large crowd was on hand to hear the Democratic presidential nominee at the National Stock Yards in National City (above right). Cheering teenagers (left) were prominent among those who watched his motorcade roll through Venice, where he lashed out at the Republican Administration's vetoes of Democrat-backed bills. First stop was in Alton (right) where he spoke despite heavy rain to a wildly cheering crowd of 2000 persons in the city square.
