This document discusses three magazine advertisement designs for Irn-Bru:
1) The first design was basic and only featured a can and bolt collaborating well.
2) The second design had a better theme and included key features like the brand logo and catchy slogans to make it suitable for use as a poster.
3) The third design continued the theme of using humor, featuring a man running for gold with Irn-Bru's help, though the fonts and colors were not entirely satisfactory.
