This structure, officially known as the Benjamin S. Rosenthal Post Office Building (it was renamed for a former congressman whose district office was located in the building), looks like it's in better shape than it was a year ago.
According to its listing on the National Register of Historic Places:
The building is the most distinguished of the Colonial Revival post offices erected in New York City during the 1930s, one of the most prolific periods of post office construction in the nation’s history. . . .
In addition to its architectural significance, the Flushing Post Office contains an artistically significant mural which runs around the entire lobby. This mural was commissioned by the Public Works of Art [Project] from Vincent Aderente and executed in 1933-4.
