Is this dinnerware set dishwasher safe?

We were going through our Christmas stuff today and found a 32 piece snowman dinnerware set made by Thompson Pottery. This link shows what set it is: http://www.mimisbackporch.com/catalog.php/bluebird/ct/pd1393727/Snowman_Blue_Speckles_Sky_Christmas_Dinner_Plate_by_Thomson_Pottery_Retired
Does anyone know if it is dishwasher safe?
