Nasco Springtime Jelly service w/ spoon 1940’s Japan?

In original condition, this beautiful Anthropologie like serving dish originally for jelly, but would work for mustard or dips to be served on a plate. Doing a little research, it seems like these were made in the 1940’s in Japan? Absolutely beautiful! Please see my other listing in the set to bundle and save! Perfect for a tea party! No chips! All pieces have some wear and crackle. See photos!
