Have to decorate a brochure…?

For my Geography class I have to make a brochure about Saguaro National Park,Arizona. I’ve made it on Microsoft office publisher. However,I want to add decoration to it. Not from the computer. Could someone please give me ideas? I want it to look sort of like a page from a scrapbook,or something catchy that would make you want to look at it.

If you have old National Geographic magazines laying around you could cut out pictures that resemble the park in Arizona. A collage might look neat if you mixed in some cut-out pictures with the writing of the brochure.
