Normally, the sculptures you hear about at the Iowa State Fair are made of butter. This year there was one of sand that might be of interest to Beat regulars. “Surprise Party” is a sand castle sculpture that shows the Three Little Pigs having some guests over to meet the Big Bad Wolf: pig versions of the Avengers and Justice League. Superman, Batman, Wonder Woman, Thor, Captain America, Iron Man and Spider-Man. Or is that Spider-Ham. This looks like a job for Peter Porker, after all.
