Gerda Stromberg vases, one with Gunnar Nylund decoration.

Strombergshyttan, Sweden.
Floral glass/vase on foot.
Model number: B 286 by Gerda Stromberg late 1930s.
Engraved bird decoration C 669, probably by Gunnar Nylund late 1950s.

This Gerda Stromberg vase is a typical Strombergshyttan piece. Still in production into the 1960s. Another similar model on foot by Gerda Stromberg from about 1938-40, B 335, were still in production to at least 1977. The engraved motif with flying birds is probably by Gunnar Nylund according to the C-number. It's in an intervall from mid-late 1950s were all engraving motifs (as I believe) are done by Nylund. In that time Gerda Stromberg did not draw anything more, and Asta Stromberg did not draw much engraving motifs what I know. The last picture shows the same vase model, with another simpler engraving motif I think is a decoration by Gerda Stromberg, with an F-number (grinding/cutting decorations).

The vase with the flying birds has a fine engraving work, produced in classic engraving technique with fixed copper wheel. Strombergshyttan had some skilled engravers who mastered that method to perfection. In 1963 Rune Strand came from Kosta and introduced his invention, the dental drill technique, to Strombergshyttan. But the classic "fixed copper wheel" method was used in Strombergshyttan until the last old engravers retired about 1970. I saw myself both Tord Abrahamsson and Ragnar Bergqvist engaving with fixed copper wheel in Strombergshyttan under the whole 1960s. So this vase can be produced somtimes between 1957 - 1970 as I see.
