The vase decorated with daffodils in the De Witte Zwaan collection is decorated in the Art Nouveau style. The meandering plant motif on the bottom rim of the vase and the graceful, thin stems of the daffodils are characteristic of the art style of that period. All Heckert products are marked with the initials FH, including this vase. A number often follows this initial, indicating the product and the production run.
