How to dosobirat collectibles? (Mafia 3)

People. So much garbage. Passed Mafia III, no, not this garbage. Rushed to kill the first two guys in the casino (without spoilers) and have not collected one picture Vargas. Back in the casino, but to get to it, I can't. Is it possible to dosobirat? And another album - also can not find, and the map is empty. Just a shame it's the last two items, and everything else collected. That's all right, except for this.
