Rock and roll (often written as rock & roll or rock ‘n’ roll) is a genre of popular music that originated and evolved in the United States during the late 1940s and early 1950s. In this clipart I’m sharing 30 vector silhouettes of people dancing in this style. Also nowdays you can see acrobatic rock n roll or sport dance.
I advise you to use Illustrator CS (or higher), but you also can try to use your favorite program for editing vector files, like, PMView, Flash, Photo Styler, Xara, Corel Draw. It is so easy to edit any vector file: add something new, resize, replace shapes, rotate, recolor.
