Standard Oil Company issued this hat pin name badge for each employee to wear on their uniform daily. Each employee wrote their name on a small piece of white paper and slid it into this name badge, with a small plastic cover so it did not smear when it got wet. The plastic is no longer in this piece of history, and it has two screwback fasteners to attach nicely to a hat or shirt. The enamel finish on the logo is smooth to the touch, with a small bend in the upper right corner of the rectangle base. We date this piece from the 1920s, and it will look great in your collection. 20825-QPP
