This 1918 photograph is from the Grandview Heights/Marble Cliff Historical Society's Alleyne Higgs collection.
It shows a group of Grandview girls participating in the maypole dance, which has been a May Day tradition around the world for several centuries. Each dancer holds a colored ribbon and moves in a circle around the pole.
The pattern on the pole is determined by the choreography of the dance.
In a simple form, every other girl goes the opposite direction and alternates moving in front or behind the girls coming the other direction (inset), weaving the ribbons around the pole.
A challenge for the dancers is to retrace their steps exactly in order to unwind the ribbons.
