What does paper rag and kewpie have in common?

Paper rag and kewpie are both types of dolls that were popular in the early 20th century. Paper rag dolls were made of paper or cardboard, often with cloth clothing, while kewpie dolls were based on the character created by artist Rose O'Neill, known for their distinctive chubby cheeks and curling hair. Both types of dolls are collectible today and are considered nostalgic reminders of a bygone era.
