Didn't realize that Alembic was selling this version of the pin. Looks like it was made available around the same time as the 50th anniversary logo pin. I have one of the early logo pins which came as "case candy" with a 1982 Distillate. The early one looks different, though, and includes the Alembic name at the bottom, it may also be a bit smaller. The design of the older pins isn't quite as nice.
