In the late 1990s and early 2000s, part of Apple’s print advertising included magazine inserts. Some inserts were “mini-magazines” within magazines and others, like this example, was a fold-out poster. These inserts were glued with a pliable rubber cement that could be easily removed.
This example is an advertisement for the Power Mac G4 Cube. As the ad unfolds (literally), the cover shows a photo of the G4 Cube with the caption “(Hint: It’s a computer.).” The first unfold (2-up) reveals, “Actually, it’s a supercomputer” with five short paragraphs touting the Cube’s size and power. The second unfold (4-up) has the headline “So much technology. So little space.” and shows connections, features, and peripherals available for use with the Cube. Fully unfolded (8-up), a poster is revealed that declares, “Presenting the Power Mac G4 Cube. Actual size. Think different.” The back of the fully folded insert is another view of the G4 Cube with three available displays and the headline “A marvel of engineering. And economics.”
Folded, the size of the insert is 7.3125 x 10.125 inches. Fully unfolded (into 8 panels) the size is 29.25 x 20.25 inches.
I also have a poster version (rolled in a tube) of the fully unfolded image used in this ad (at 24 x 36 inches).
