Located in Philadelphia, the National Liberty Museum claims to be the "only Museum in the world featuring contemporary glass art to represent the fragile qualities of freedom."
That's what I call picking a market niche :-)
If you can make it to the city of brotherly love sometime between August 9-31 you're likely to be in for a treat. "Glass Down Under" promises to bring a wide selection of art by such well regarded glass artists as Scott Chaseling, Kirstie Rea, Pamela Stadus and more. Access to the exhibit is included in standard admission.
The museum's permanent collection features work by Dale Chihuly and Stanislav Libenský/Jaraslava Brychtová among many others.
