Mayor Michael R. Bloomberg made one more permanent alteration to City Hall on Monday: hanging his official mayoral portrait.
The painting, by the artist Jon R. Friedman, features Mr. Bloomberg standing in front of the bullpen, his beloved open-format office on the second floor of City Hall. Similar to a Wall Street trading floor, the bullpen is a format he imported from Bloomberg L.P., his company.
Elements of Mr. Bloomberg’s life dot the background of the painting. His daughters, Emma and Georgina, can be seen in a photo on his desk in the bullpen, just to the left of Bloomberg’s left hand.
His tie is purple â€" the color of his political affiliation â€" Independent and bipartisan, the color in the middle.
There are Bloomberg computer terminals all over the room.
At the back of the room is a giant TV with a 311 system update on screen â€" of calls made so far that day (121).
