Have you been searching for Bayle, or Baylor? You'll want to research
the history of Bayle Peanut Butter, as it is considered as the first peanut
butter ever made and sold commercially.
I believe that initially it was in a tin tub, and so far I've found no mention
of it being in a glass jar. They began selling it around 1890, but as to when
they began to pack it in jars, I have no idea.
