I kept on looking for more wordless books and came up with this list. These are by no means all of them. Please share if you know others.
Some of these books come with sequels like the Carl's Jack's and Daisy's series. Others are all from the same author, like Barbara Lehman or David Weisner.
These are books worth a phone call and a trip to the library. Some are better if you buy them because they are great for other areas, but you need to be the judge of that. I try them a the library when I can and then buy when I find them necessary. Also let me tell you, if you don't already know, that just because it is a picture book, it does not mean it is a good book for little ones. I found some of Weisner's and Lehman's books to be not a good fit for my personal taste as they are confusing, and with ideas that can actually scare my three year old! So be cautious!
I found this gem of a wordless book at our local library: Flood by Alvaro F. Villa. It has beautiful images and a story that will touch your heart.
