My favourite picture of ABBA.
I think the image just says it all for their relationship between each other midway through their time in the band. Agnetha and Björn have been married for a while now and Benny and Frida like 2 years before they are married. I think it shows the vast differences in each of their relationships and also gives a visual to a lot of lyrics in their songs.
…I love ABBA if you didn’t know.
