Children playing with skipping rope

The action in this little film is clear enough, even if the context remains a mystery.

Two men encourage children to play in a park. On the far right, one twirls a skipping rope, while in the centre left another cajoles a youngster to play in frame; the child later runs across the frame in a huff. The action in this film is clear enough, even if the context remains a mystery. In instances like this, the slightest insight can help unravel the mystery. Where is this park, for example? An answer to that could help solve questions such as: who made and distributed the film? Who are the children in it? And are the two men dressed identically by design or coincidence?
