Mighty Mouse sort of comic strip

This looks like a daily strip but actually was done for an oblong book of mighty mouse cartoons 1981 was when the book was published
I am not sure if this is a tryout strip that was done and then republished or expanded into a book or it it was just done for the book. I got it from Tallarico's estate so I couldn't ask Tony- he did it from the group that owned the rights to the character. At the time i figured it was a short lived strip and only alter discovered the book ( which was too expensive to buy!) I grew up on Mighty mouse so it was fun to have anyway
