In 1928-1929 a variant cover has been seen in all of the Wee Books Series. Here is an example from the Wee Books Peter Rabbit Series. Note that the variant cover has an applique that encompasses the entire front cover. I have placed a picture of the more commonly seen cover next to it. It can be seen that the full cover applique duplicates the cloth/applique cover perfectly.

This cover variant is quite uncommon.
