Boy, was I wrong with my guesswork. This is part of the "Aphrodite" series produced as part of the "Artist Collection," which was intended to be glass that was "a little more adventurous" and created by either Bertil Vallien or Ulrica Hydman-Vallien. It was originally given a production number. This looks like either 48533 or 48534, depending on its size. So designed in 1985.
The question is whether the Atelier series was before or after the the production series. My understanding of the coding system (limited) can't make sense of these numbers. A close up of the label would give us an idea of time of production.
