At the risk of hijacking this thread, I feel that I need to provide another view of the West Virginia Museum of American Glass and their excellent journal - All About Glass. Unfortunately, the All About Glass forums have indeed been over run by spammers. But do not let that scare you away from this great organization. Their main website can be found at
http://wvmag.bglances.com/. You can subscribe to the journal through the web page provided above or through their ebay store.
That said, the jug that this thread is really about is not Old Charlie. There was a very good article about "Old Charlie" in All About Glass Vol. 1. No 1. Back issues are also available from their ebay store.
