Though we have no real confirmation other than the appearance of a bridge in the background towards the right, this appears to be an early photo of Bayfront Park’s humble beginnings.
Here you can see the shoreline with a walkway adorned with benches and tons of palm trees. You can see a man reading a newspaper on one of the benches. And on the walkway, four people, including a couple taking what we can assume is a romantic stroll.
And one more photo below from a nearby angle as well.
