Port Prosperity Station - Telescope #9
Just before taking the gondola to Emporia, head to the walkway opposite the Gun Automaton tear. Over here is a Telescope that will give you a great view of the gondola's destination.
The Salty Oyster - "Lutece's Brother Arrives in Columbia!"
On your way to Comstock's house (just before entering Grand Central Depot), you'll come to a small courtyard. On the right side from where you enter is The Salty Oyster bar. Have Elizabeth pick the lock to give you access, then head to the back right of the building. Between the bathrooms, you'll find this Kinetoscope.
