We have been set a project to create a poster for the 2010 Winter Olympics so I have found some of the actual posters from these games and also some of the ones from other games.
This is the official poster of the games

This information about the posters comes from the Vancouver 2010 website
The official poster is one of the most coveted collector’s items of the Olympic Games and has had a place in history starting with the first Games poster in 1912.
The Vancouver 2010 official poster represents both the beauty of the Host Region and the spirit of Canada’s Games. Cropped within the shape of a maple leaf, the bold Vancouver 2010 graphics are inspired by Canada’s cultural and environmental diversity as well as the energy and spirit of the Canadian people.For the first time in history, both the Olympic and Paralympic Winter Games official posters are represented in a unified manner; when displayed together, the two halves of the maple leaf join to create a whole.
The Olympic games also has some mascots and these are on coins and cards.
Sumi, Miga & Quatchi are the mascots seen above on the coins.
The site also uses some sports graphics
