This is an antique glass paperweight showcasing a large building. The building is not identified in the image inside the paperweight, however I think it might be from the 1893 Chicago Columbian Exposition and might be the Brazilian building. The image within the paperweight has tiny mica or shell insets that accent the building. There is some internal degradation/discoloration to the image at the lower corners. The image is held in the paperweight with a glued backing of leatherette paper. There is a tiny chip on the upper left face of the glass and an internal bruise on the left lower side edge of the glass. This is still a wonderful antique paperweight that is of the late 1800-early 1900 era.
