Hard to tell from the pictures but there's a design on the smallest inside square.

This wallpaper was easy to install and work with. Looks great!

I haven't yet installed the wallpaper, but I can report that it looks like the picture. I deducted a star because the description is wrong. The squares are not 21 inches on a side, 21 inches is the repeat (4 squares). Each square measures 5.25 inches per side. I did not want large squares and a photo included with a customer review was the only way I could determine that they must be smaller.

love it! great quality and easy to hang.
