The assumption underlying my original declaration of awesomeness was that this postal receptacle was a unique, and quite substantial, celebration of the first letter of the resident family's last name. In the months since I took this photo, however, I have spotted several similar mailboxes around the five boroughs. Apparently, this is a common design that normally cradles a round-bottomed flower planter. Of course, I can't rule out the possibility that these folks actually are a C family, and that they've converted a formerly planterized mailbox into a three-foot-high expression of family pride. While such an act would certainly lie toward the awesome end of the spectrum, I don't think it would be sufficient to raise this mass-produced contraption to the level of official awesomeness.

C even in NYC you keep finding awesome mailboxes.
