Hello Glass Lovers...
We are the International Depression Glass Club, of Sacramento, California. Actually, our membership comes from all over northern California, and indeed, from several other States as well.
The club was established many years ago, when so-called "Depression Glass" was a hot new collectible. Members joined together to share information about the various items of American-made glassware, primarily from the "Depression" years (roughly the late 1920's through the end of WW II). When the Club was organized, there were few, if any, books on the subject, and one of the best ways to learn about the glass was to share information with other collectors.
The founders also organized a "Glass Show," which is similar to an Antique show, except that all the vendors sell is glassware. At the time, "regular" Antique shows wouldn't permit dealers in "Depression Glass" to exhibit at their shows, so collectors organized "Glass Shows" in order to be able to buy and sell "Depression Glass." The IDGC was one of the first clubs to organize a show, and now has the distinction of having the longest-running show in the country.
