This website is particularly useful in viewing past design publications for the Olympics, it ranges from 1964 to 2012. I found it interesting because it shows the underlying color themes, positioning, styles, structure of the different years. Scrolling through the page, you get a sense of the branding style through how the publication appears, e.g. bright colours portray the event to be busy, block dark colours portays the event to be formalistic e.g. Barcelona 1992:
It appears that most countries have used a simpistic style however, Nagona 1998 uses images and vivid colours:
Personally I find Nagona 1998 to be the least aesthetically pleasing because the colours used do not compliment each other and I find it too brash, there is not a consistent style or layout. But the designer could have chosen this idea because they wanted to distinguish their designs from the rest of the other designs. Personally the overuse of overlay with low transparency on the text makes it distracting to read the main text and get an overall impression of the publication.
