On the diagram the pieces describe a cycle of Eiffel paralysis:
wSe3 paralyses bBf5 who paralyses wRg6 - bQc6-wPc2-bSd3-wBe5-bRg7-wQd7-bPd4-wSe3.
The two Kings exploit these specific Eiffel paralyses in two distinct marches in each solution:

The spectacular key offers two flights and opens the black royal battery. Three checks by the black King follow with spectacular counter-checks.
The problem is reminiscent of Novejarque's 1st Prize in the same magazine in 1930 but it is definitely an improvement.
