Willoughby Studio was a small California pottery !! Found several of their items but not much history !! Willoughby Studio was started by Gladys Burbank in the mid 40`s and sold out to Gracetone in the mid 50`s !! Gracetone was then bought by Frankoma Pottery!! Several listings for Willoughby Studio items in the link above !!

I have include another picture. Thank you.
