Nice shiny old threadless. Warped base from not quite enough glass poured in the mould. Some small nibbling around the base mold line, and maybe a 1.5" total of shallow flake chips on the base. Micro fizz and several wisps of steam work their way around inside. There is a dark amber inclusion of something, a wisp of steam, and a big bubble, which all conspired together to cause a clean, no glass missing fracture that starts at the base on one side, goes up the mold line and then hooks around most of the dome. Couple of fleabites, and there you have it. Still a nice piece of glass that displays well. $100 plus shipping / insurance.
