Old glass stone kicking game piece. There's an embossed image of a biplane on the surface. It's relatively thick and shaped a bit like a steamed bun. Overall, there are scratches and dirt, giving it a frosted glass appearance. There's a small chip on the side (please see the last photo). The line running through the center was made when the glass was cut during manufacturing, and I don't think it's a scratch. Please check the photos for other details and the size. Please read and agree to the contents of the profile section. We look forward to your purchase.
