This pattern has been heavily reproduced. All cobalt, clear blue, ruby and bright green pieces are reproductions.
The top photos are close ups of a reproduced pitcher. The close up shows the reproduced pieces lack the detail of the original pattern. The leaves are too uniform in the reproduced pieces.
The bottom left photo is the base of the butter dish and it also shows a less detailed pattern.
The bottom right photo is the tumbler which is easily identified because the line separating the pattern from the rim is single and it has three lines on the original.
