I recently acquired these photos at an antique store with no ID. Can anyone help?
Scanning through samples of the List of US Destroyer Classes and List of US Cruiser Classes for examples of the 2-and-2 funnel arrangement and unusual bow-turret combination reveals the Omaha-class (light) Cruiser as the only US warship class that fits: Note the matching 2-and-2 funnel arrangement, stacked single-barrelled casemates to port and starboard on the bow, and double-barrelled forward-facing turret. This combination of features is unique to the Omaha class amongst US Destroyer and Cruiser classes, and the gun configuration is repeated at the stern.
Commissioned vessels of the class comprised the following:
Here is another clear picture of the bow of USS Omaha itself in which the similarities can be identified clearly (from Old Ship Galleries):
I have reviewed all pictures in the Old Ship Picture Galleries under the names beginning with Omaha and Detroit, and confirmed that OP's pictures are not in that collection under either of those names. If others might wish to check the remaining vessels in the class - someone might get lucky.
The next step (I believe) is if someone can identify any one of the bridge, water-tower, or hills in the background of this picture to try and identify which port the pictures were taken in. Combining that with the known service records of the vessels in the class should narrow down the candidates to one or two, with possible dates as well.
With many thanks to @Comintern, the picture appears to have been taken from the upper deck of the Steel Bridge in Portland Oregon, looking South towards the Burnside Bridge even to the still existing water tower:
