shower curtain of Boston's T map. The shower curtain, made by Izola, is a soft plastic, not the rigid vinyl we're accustomed to. And it's PVC-free! A search of the Bed Bath & Beyond website didn't yield a quick result so we headed over to the Izola website where it's being sold for the same price ($29.99). They also make a curtain with New York, Chicago, DC, and London's transit maps. We're proud that Boston made the cut!
