I thought this spread in Nylon magazine was a great example of a well designed side bar. This spread is driven by the strong picture on the left and is accompanied by the text on the right. The sidebar is text heavy, but I think thats the point. There is a sense of hierarchy, saying read me.
The editor’s want you to read about the books they are promoting. They make the association clear and simple while having a lot of text, which is difficult. -victoria troxler
