Graffiti artist Slick puts finishing touches on Roger Waters' inflatable pig backstage at Coachella. There's a $10,000 reward for the return of the pig, which was released during Roger Waters' performance.

UPDATE: Roger Waters' lost pig was found in two pieces Tuesday, according to KESQ.com.

INDIO, California – Concert promoters are offering a $10,000 reward and four lifetime passes to the Coachella Valley Music and Arts Festival for the safe return of a giant inflatable pig that's gone missing.

The spray-painted pig balloon was released during Roger Waters' performance Sunday at the festival. The school-bus-size prop emerged during "Pigs," a song from Pink Floyd's 1977 album Animals.

"A pig got loose last night," said Bill Fold, one of the festival'sproducers, on Monday. "We really like him and want him back.... It's avery emotional time for us."

The pig was covered with political graffiti:

"Don't be led to the slaughter," read one slogan. "Fear builds walls,"

read another. A cartoon Uncle Sam painted on the pig held two bloodycleavers, and the porker's belly read "Obama," with a checked ballotbox alongside, according to the Associated Press.

Waters brought the three-day Coachella festival to a close Sunday with two sets, during which he played the Pink Floyd classic Dark Side of the Moon in its entirety.
