I came home once to what sounded like a cat dying in the garage. Wanting to remove the battery, but not able to figure out how, my mother decided this was the best way to kill the battery. Yes, she is a teacher and she wanted to use this book sans annoying sounds.
Just a mobile I picked up for $2. It hails from a closing thrift store. By : Flensted Mobiles Denmark. 18 inches x 20 inches. A family company that started in 1954 by Christian Flensted and his wife Grethe. His son Christian and his wife Aase now continue the company. Their "department of space research" create some truly enchanting mobiles.
