The lesson
In a case study about a format, show the real creative at the center and let the setup and quotes sit around it.
The sheet is titled "A CAROUSEL SUCCESS STORY". Three actual carousel cards, showing $20k, $75bn and 27.5%, sit in the middle. Objectives and target audience fill the left rail, a National Australia Bank profile and two quotes the right, and a "WHY IT WORKS" row of three icons runs below.
Don't copy the vague results line, which only says the campaign beat a regional benchmark with no figure. Keep the artifact in the middle and give your results real numbers.
