Traditionally, noisemakers have been associated with the celebration of holidays and of personal milestones like birthdays, graduations, and weddings. Kids, however, know no such restrictions--any day in which you have a noisemaker in hand is a suitable occasion for noisemaking. The development of chromolithograph printing on metal in the twentieth century made noisemakers much more colorful and, thus, appealing to children--but, fortunately for parents, no louder than too loud.
