Hello, people. Well, I don't know if anyone mentioned this yet, but this is possibly the first easter egg of Mafia III. Basically, here's a link to a video: https://www.youtube.com/watch?v=qAHAbd72CBQ - At about 00:58 into the video, you can see woman with a purse. Don't know if it's just me, but I believe this woman is a reference to Forrest Gump. The main protagonist's Forrest Gump's mother actually.
EDIT: https://www.youtube.com/watch?v=0gNe-Nlx4yk In this video at 11:19 (Either this one or the Mafia Game channel's video) you can see what I assume is the same woman from the previous trailer, talking in the southern accent, the same accent Forrest's mother had in the film.
