The item on the left is the "Covered Sugar". On the right is the Covered Butter.
This pattern is becoming very hard to find today. Most pieces will be signed with
the Northwood trademark N inside a circle. The ad below shows
this pattern and the line was called Golden Opalescent.
Note: Blue Opalescent was made in this pattern but it is a rarer color. Another pattern
Northwood made was called Lustre Flute. This line was also called Golden Opalescent. Blue and White Opalescent were the only two colors listed
but we know Green was made as well and it's a rarer color in this pattern. See Lustre Flute
