Sprayground, the brand behind the shark-mouth backpack, has licensed U.S. Postal Service symbols and trademarks for a line of bags and toys sold in a pop-up inside the columned Farley Post Office across from Madison Square Garden. It is an unlikely collab in an unlikely room, and the building alone is worth the detour. If you collect bags or just want the strangest souvenir in Midtown, this is your last weekend to shop it in person.
What to expect
Head into the Farley building on Eighth Avenue, the Beaux-Arts post office facing Madison Square Garden, to find the Sprayground shop. The postal-themed bags and toys are the whole focus, so a visit is a browse and a purchase rather than a timed experience.
Good to know
- The A, C and E at 34 St–Penn Station stop across the street, and the 1, 2 and 3 are one avenue east.
- The shop is inside a working post office, so expect mail customers and daytime foot traffic from Penn Station.
- The collection also launched on Sprayground's website, but the in-person shop is the draw for the building and the display.
- Pair it with a walk through Moynihan Train Hall, which shares the Farley building's footprint.
- Check the listed schedule before you go, as the shop keeps shorter hours on some days and is dark one day each week.
