Wallet card with a 60-year-old bus

The MTA's vintage bus project seems to be getting smaller each  year. There were only four different buses and they seemed to be barely on the road this year. I caught a glimpse of each bus at least once but only one time was close enough to take a photo. This is the 1959 General Motors TDH-5301. Hopefully I'll have better luck spotting them next year.
