On August 6 and 7, 1963, the local papers reported on Hiroshima Day events in Pittsburgh. From the Pittsburgh Press on the 6th:
Paper cranes on helium-filled balloons -- symbols of the children who died 18 years ago during the bombing of Hiroshima -- flew high above Gateway Center today.
The paper birds were sent aloft by a group of Pittsburgh women as reminders that today's children still face the dangers of the nuclear arms race.
The Pittsburgh Women for Peace, Women's International League for Peace and Freedom and the Society of Friends sponsored the outdoor observance of Hiroshima Day. The groups are urging support of the nuclear test ban treaty now awaiting ratification by the U.S. Senate.
