Signed and Unsigned Pieces - Help Please

I have a few pieces of singed and unsigned pieces that belonged to my late uncle from his antique store in Arkansas. They were boxed in the late 80’s and eventually were passed down to me. I would love to find out more about the pieces and have no idea how to find out until I came across this site. I will post pictures shortly. One has initials W.Y. and one has a signature but I can’t interpret it.
