On May 1, 1973, there were several May Day demonstration with several participating organizations. I came to photograph one of them.
The demonstration began at Drottningtorget, went up Östergatan and then turned into Djäknegatan with a detour to Gustav Adolfs torg and then they returned and went over Amiralsbron on Amiralsgatan as far as Bergsgatan. There the demonstration followed Bergsgatan towards the final destination at Möllevångstorget.
The picture shows the demonstration walking on the bridge Amiralsbron towards Möllevångstorget. To see more pictures from demonstration in the early 1970s see my project site I made when participating in a course in digitalization.
