This print is featured as an unadvertised bonus to Kino's magnificent cinema collection "The Movies Begin: A Treasury of Early Cinema" in the second volume, namely "The European Pioneers." The reason they call this an unadvertised bonus is because the print survives in a most faded and blurred condition, thus it is below Kino's standard quality.
In this very short short we see a girl being pushed on a swing on a stage by these other two women. I don't get it. Why did they title this "Girls Swinging"? Is the film I have seen actually "One Girl Swinging" from the same year and same company? Why is the swing on the stage? Why not go on location? Couldn't the girl swing herself without being pushed? This is very baffling. I suppose this was meant to be sexual, but today it comes off as silly and very harmless. One thing to note is that the same year Melies made "After the Ball", which makes you wonder which short came first.
(Note: I plan to later review the nine other unadvertised bonus features as well. This is the first of the ten).
