Vintage, Dugan   Updated 12/19/2011   Comments by Alan and Lorraine Pickup

The pattern is easily confused with Fenton's Vintage pattern but there are distinct differences. Dugan's will have the dome base and a break in the pattern between two bunches of grapes. In addition, the pattern is more concentrated toward the center of the bowl than with the Fenton. The bowl above left is somewhat deeper than the usual ruffled Dugan examples.

Both the powder jar and perfume bottles are Dugan--though the powder jar is often attributed to Fenton and the perfume bottle usually is designated as Grape and Cable and assumed to be part of Northwood dresser sets. There is no cable on the bottles (or the powder jar, for that matter).
