KOG is Kokomo Opalescent Glass in Indiana, and this gem of a paperweight was made by Michael Amis and Jon Wolfe of KOG. An awesome ammonite creation is embedded in inside along with other seaforms, soooo cool in its 3D form!! There is great depth to the design, really nicely done! I love this piece, so hard to let go of. Signed 'KOG WPW 002 LB 3101'.
