Information About Anker Keramik Item?

I found these tiny bowls (ca. 3") at a thrift store the other day and I can't find any information online about the maker. The box is clearly marked "Anker Keramik" and each bowl has a Denmark stamp with an anchor. Each image depicts an astrological symbol. Can anyone tell me anything about these?

Like so?

Maybe these might help if you contact them

Anker Keramik in Nykøbing, was founded in 1944 by Anker Nørregaard, who worked as chief designer of Hegnetslund lervarefabrik between 1933 and 1944. He used the name Anker Keramik already in 1930 and he produced decorated or undecorated household wares and figurines. Since 1952 he works together with Kamma Nørregaard, who is responsible for the decoration.
