Tumblers were sold with Big Top peanut butter in them.
A discussion in the chataboutdg forum initiated by Tom Felt in July 2020 concluded that no definitive source (not Hazel-Atlas, Hocking, Jeannette, etc.) has been found. Per Tom Felt:" At the moment, [these] are unknown. There's no documentation for them that we've found linking them to any of the usual suspects."
The old Big Top Peanut Butter magazine ads refer to the pattern as "Early American" in quotes.
