The Sanitation Department is evicting this collection bin (belonging to the controversial Planet Aid organization) from the public sidewalk on which it has illegitimately taken up residence. If it doesn't make itself scarce within 30 days, it will be condemned and hauled away under DSNY's Derelict Vehicle Removal Program.
It's more fun if you say it louder.
(You can see Astoria's version of the Flatiron Building reflected in the window.)
