I thought that about "articulated", too, Dave, and had to look it up as well...it does mean "connected by joints", too! (I was surprised! - you learn something new everyday, I guess 🙂 )~ I also looked up descriptions for those children's book (I have some antique ones) that have the tabs where you can make different things move, and those were just referred to as "moving picture books" - Anyway, it's a great piece, Judy - moving, mechanical, articulated, whatever :x !
