Here is a rarely seen Clinton labor button, made more impressive by the obscurity of the union and the fact it no longer exists in this form. The Oil, Chemical & Atomic Workers Union began in 1918 as the International Association of Oil Field, Gas Well and Refinery Workers of America. The union went through a few name changes before settling with OCAW in 1955. In 1999, with a membership of 80,000, it merged with the United Paperworkers International Union to form Paper, Allied-Industrial, Chemical and Energy Workers International Union (PACE).
Not much is known about the buttons. It came from a local rather than its international headquarters, but I don't recall the location of Local 1 - 895. The quality of this 2 1/4" cello is quite good, and the pure white background was distorted by the scan. There may be only two known in the hobby, and with the union long gone finding one now would be a matter of pure luck.
