We can all be heroes this Halloween with UNICEF

Children trick-or-treating with UNICEF USA boxes.

The beloved tradition of trick-or-treating on Halloween began in the United States in the 1920s, and has gained in popularity ever since. In 1947, Clyde Allison, who was a Presbyterian pastor in Pennsylvania, and his wife Mary Emma Allison, a teacher, came up with the idea to ask children to trick-or-treat for charity.
