A curiosity from 1972 - A-frames in Munich!

Sadly, the rhyme or reason for their installation would appear to be lost to time.
They weren't installed when Bayern Munich won the Bundesliga on the last day of the 1971-72 season, and the standard Olympiastadion box nets were back for the Olympics later that summer.
Ajax were in the middle of their European Cup three-in-a-row at that time so perhaps we see the influence of Dutch football in the shape of the stanchions - check out PSV Eindhoven, for example.
They're awesome A-frames.
Just, what were they doing there?
