Rorstrand Sweden Demitasse Set

Lovely vintage green ribbed Rorstrand Sweden demitasse cups and saucers. While not art for arts sake, the simple, subtle, curved lines of these cups and saucers are art to me. I just got this set of 6 perfect cups and saucers at an estate sale, and, the price was less than the cost of lunch at some fast food places - is that gauche of me? ;) Anyway, while I believe these were made in the 1950s, I can only find Rorstrand Sweden demitasse ribbed cups with flowers, not in a solid color. So, I hope my cups aren't fake because I love them. I really don't think they are fake because the home from which I bought them was a bit frozen in time and had numerous other items from Sweden. Many items from this family's travels were labeled with the name of the family member who obtained the object during travels around the world, and the location and date obtained.
