Here is two vintage Tupperware made in U.S.A. cereal bowls. They are both marked 890. To me they look yellow, but are classified as the "Harvest Gold" pattern. The bowls show normal signs of wear.
The top diameter of each bowl is about 6 inches. The base diameter is 3 1/2 inches, and the height is about 2 1/4 inches.
Please check all the photos given.
