My best guess is that Po-mack was around 68or 69. It was packaged in a sophisticated little bottle that reminds one of a wine cooler bottle of today. like I said, I have asked several so-called collectors of memorabilia if they had ever seen or heard of this bottle; they all said no. A previous message said they thought it was in the early seventies. It well could have been, because I remember not being able to find it anywhere, but in Union county.
