Each year, Lions clubs around the world proudly sponsor the Lions International Peace Poster Contest in local schools and youth groups. This art contest for kids encourages young people worldwide to express their visions of peace. During the last 20 years, more than four million children from nearly 100 countries have participated in the contest. The theme of the 2010-11 Peace Poster Contest, "Vision of Peace," was open to students, aged 11, 12 or 13. Participants use a variety of mediums, including charcoal, crayon, pencil and paint, to express the theme. The works created are unique and express the young artists' life experiences and culture.
