Pre Beutron and Beauclaire branding
I suspect that ‘Bonnie Buttons’ were a brand name used by G. Herring pre 1946, before the name Beutron was used. However, I cannot confirm this.
Likewise, I suspect that all buttons on cards bearing borders of vine leaves were made by General Plastics from around 1941-1950, after which the Beauclaire name was adopted.
