My rotary phone.
(Ignore the date stamp. This from, like, late 2008, early 2009, but I hadn't learned how to fix the stamp on the camera yet.)
I got this at a thrift sale for $5. It still works, but the ring is so loud that it scares me half to death and wakes me up if it rings while I'm sleeping, so I can't keep it plugged in. But it does work.
Peace and cookies,
