A yellow cab in needlepoint, checker stripe and all. The shorthand for New York that does not require printing the words on anything.
It clips on with a lobster clasp and moves between a tote, a carry-on, and a keyring in seconds, which makes it a natural for a bag that actually travels. The needlepoint face has texture that photographs well and will not scratch leather when it swings.
Buy it for the friend who moved there, the one who goes twice a year and talks about it constantly, or as the souvenir you wish the airport gift shop had sold you.
Cluster it with the passport and the postcard charms for a travel set, or let it hang alone on a black bag where the yellow does the work.
