I think a good addition to a collection of writing instruments that were unique to the twentieth century would be pens and pencils like we have now because back then they dipped feathers in ink and then wrote with them. They were very special because people wrote there feeling and grocery list and drew thing as art. And maybe more to add on would be paint brushes to make beautiful art like they did back then. I hope this helped u and that all your questions are answered.
Whats the question?
I mean yes it was an advancement .

As the the French Academy was divided rather sharply between two doctrines. One taught that form was the most important element in the painting (Poussiniste) and the other taught that color was the most important element (Rubeniste), the rococo artist follow <u>doctrine of color.</u>
