Mel's Whistle for Carl Harold and the Purple Crayon

This is Mel's whistle he uses to call Carl in Harold and the Purple Crayon. There are three of them, all pretty much identical. It is not possible to tell if these are the one on screen or not but they were production used and all have minor wear. These came from a box on set labeled "Mel Box" along with his other items. Box not included. Each whistle sold separately.
