In 1972, some of the posters for Democratic presidential candidate George McGovern's campaign were intended to be inspirational and appeal particularly to younger voters. N. Schneider designed a series of posters for the McGovern for President Committee, all of which were colorful, exuberant, and stylized: one was dominated by a drawing of a leafy tree, accompanied by the phrase “A time to grow in a world of permanent change.” 

In 2008, artists are also working to create imagery that symbolizes the themes of Barack Obama. One, Scott Hansen, also used a stylized tree in a poster for this year's Democratic candidate for president. The tree grows out of the Obama logo, with people joining hands around it. As in McGovern's campaign, "change" is a key word, along with "hope" and "progress."
