WOW isn't that a decorative bowl. Made in Germany......so it must be pre 1956 or after 1980 as it is not West Germany the impressed mark is simply Germany. Other than that to quote Manuel, the waiter, "I know nothing"

Unfortunately a crack  has been discovered in the bowl but that does not detract from the overall appearance. It can only be seen on the outside of the bowl and runs from the rim almost to the foot.

But, I do know it is so very pretty.
