States - US Glass
According to the late John Britt, States was the final pattern in a series that was named for each of the states--only a few of which can be found in Carnival. A butter dish, an 8-inch oblong bowl and a three-handled bonbon in green are pictured.

Below is an ad for the "States" pattern from a U.S. Glass catalog. The pattern in the ad looks like the pieces above with the exception that the finial on the butter dish is different.
