These photos were provided by Richard Whitehead.
His uncle T. R. (Rudolph) Whitehead served as a Chief Boatswain's Mate
aboad the Philadelphia.
. September 29, 1941: Change of command party
at the Hotel Astor in New York.
Captain Vance D. Chapline was
being relieved by Captain C.J.Moore. 
Here are closeups of the above picture.
While we originally thought the photo below was also of the Philadelphia
crew,
this is not possible since the Philly was bombarding Southern France on that
date in 1944.
Other possibilities are Chief Whitehead's other assignments:
Chateau Thierry
AP-31, General W.A. Mann, AP-112 or the Titania AKA-13
or his brother's ship, the USS Plunkett.
Here are some closeups of the above picture.
