Ceramika Artystyczna Factory has been in operation for 70 years. Originally the artist who created a design painted the shape themselves in the way they intended their design to look.  Later, as demand grew,  the design artists had  others from the factory, sometimes other design artists or students who learned how to cut the sponges and paint their designs.

Unicorn pieces were originally painted by the design artist and are recognized by the signature and the clock number stamped on the bottom.
