MetroCards as art

My current 30-Day Unlimited MetroCard is hardly a work of act. On the back, it says “Si ves algo, di algo” and gives me the MTA’s standard anti-terrorism message in Spanish. But over the years, the MTA has released many special- and limited-edition MetroCards. As Vincent M. Mallozzi of The Times told us over the weekend, memorabilia buffs have been collecting and trading MetroCards for years. I love stories such as this one. It’s a reminder of the joys — and quirks — that can arise from something as simple as a MetroCard.
