Looking at exhibition pamphlets…
I found these a couple of sites that have a massive variety of leaflet designs.
and this one.
These helped me think more about the leaflet itself as an object, and how I could play around with it a lot more. Different shapes, folds etc.
I also went to the Tate to see the Rauschenberg exhibition, so picked up the guide for that, as well as the Wifredo Lam one. The Tate exhibition guides are quite simple but with a nice wrap around cover.
