When I previously blogged about the Bank Street bike racks, I neglected to mention (because I didn't realize it at the time) that the racks are each engraved with the name of the artist at the lower-right corner:
This one, in front of Herb & Spice, is by Mana Rouholarnini.
Robin Kelsey posted some photos of the racks after I'd prepared this entry but before I posted it. See his excellent photos here
