Heisey Rosalie was one of the more popular Rose patterns of the day and the "dolphin" feet are a giveaway as to who was responsible for the manufacturing. This set was probably identified by a paper label, since the famous diamond H is not on either piece. But....by just looking at the craftsmanship and quality, it's fairly easy to identify this set as Heisey. Both pieces are in excellent condition, but the cream pitcher does have one manufacturing anomaly on the bottom.
