While it's more of a museum than a place from which you would realistically buy anything (due to the exorbitant prices), it is well worth a trip to this little glass shop in the West Village with the curious name of "The End of History." They primarily sell glass vases, seemingly specializing in milky opaque glasses in vivid saturated colors. Set out on beautifully designed furniture pieces from the 50's, 60's and 70's the shop has a distinct vintage flair.
Their wares are organized by color, thus having the effect of a beautiful glass rainbow as you stroll around the shop. Vases come in all shapes and sizes and are mostly American, Scandinavian or Italian in origin. The shop is on Hudson Street at Perry.
