GRAND RAPIDS, MI.- Officials of ArtPrize, a radically open art competition giving away the world’s largest art prize, have announced the 2011 registration dates for venues and artists and special dates for submitting art to be installed in the Grand River. ArtPrize 2011 will run from Sept. 21 through Oct. 9. “The artist and venue registration process was developed during the last two years based on feedback provided from artists, venues, city hall and ArtPrize visitors,” said Rick DeVos, ArtPrize founder. “A lot of the most memorable work in the event is created for a specific space,” said ArtPrize Executive Director Bill Holsinger-Robinson. “Artists will know all the available venues as they register.” Holsinger-Robinson cautions artists, “The vast majority of artists who did not secure a venue in 2010 were the ones who signed up at the last minute. Register early.” Any art propos
