Margaret DeForest's ceramics hobby became a family owned business in California in 1950. The company shut it's doors in 1970.  DeForest of California is a company that tried to go against the rising trend of Japanese products that started coming ashore about the same time as the company started. DeForest was apparently successful for at least some time, as they stayed in business for twenty years and employing as many as 80 people at their California plant.

The Deforest big and baby sister set came in yellow, pink, turquoise, black and brown.  The baby is so unique the way she jets off he wall.  The set is real thick and heavy.  There is no mark on them because they came in a box where the label was on the box.  The way DeForest does their eyes, even on their anthro pieces, is very unique.  They are big eyes with a big black eyeball.  No mistaking a DeForest piece because of the eyes!  Some people pass this set up because it is so "different" and often expensive due to it's rarity.  Anyone that has owned this piece and seen it in person will tell you it makes a very elegant statement on the wall in any color!  No other manufacturer made a set anywhere near the design of this one. 

The ones that look like Spanish dancers on the right aren't marked either but they are made by Deforest.  They are much thinner than the set on the left.
