Supreme.
A Canarsie-bound L train, decked out in a brand new Supreme brand wrap, is seen approaching Sutter Ave station. Typically wrapped trains are only seen on the 42nd St Shuttle, but I would guess that Supreme's target audience rides the L much more often.
The abandoned trackways above and to the right of the train are of the former Fulton Street El, which curved east here over Pitkin Ave. The elevated line was torn down in stages between 1940 and 1956, and was replaced with the Fulton Street subway, which carries today's A and C trains.
