Anyone recognize this logo?

Spending time on the Cape keeping my father on schedule for his chemo treatments and cleaning out my grandparents' house, where some squatters trashed it then left owing 6 months rent. They could have paid if they laid off the Fireball (in the pic I moved a couch to find 30+ empty pints behind it and that's after the other 50 or so I found hidden here and there). But anyway, I came across a big crock my grandparents had covered up in a corner of the basement. It has a logo on it we can't identify. I don't know if it's especially old or what, but it's pretty cool looking. Wish I had the lid, too. Anyone ever see a logo like this? Does it mean anything or just an artist's touch?
