SAN DIEGO (CNS) - Three large sculptures by renowned French artist Niki de Saint Phalle were unveiled Sunday morning at the waterfront park in downtown San Diego.

County officials said the colorful sculptures, which range from 9 feet to 18 feet tall, are on loan for up to a dozen years from the Niki Charitable Art Foundation.

The 10 a.m. unveiling in front of the County Administration Center will be the start of a five-hour event designed to celebrate Mother's Day and give

summer an early welcome, with live music, food trucks, zip lines and children's activities, according to the county.

Among other things, a children's crafts station will be available to make Mother's Day gifts. A "Mom Zone" will offer massages, a photo booth, a flower and a sweet treat as long as supplies last, according to the county.
