The Passenger List booklet handed out to the passengers in the First Class Cabin. John & Dolores were travelling incognito albeit the only couple being from Hollywood!
The Keystone Diary which Jack and Dolores both wrote in and was dedicated to Dolores' mother.
The first entry on January 1st 1929. John writes ;-
Mama Darling -
The sea air is doing your bastard son in law lots of good and Winkie Dink is the belle of the boat -
Much love

Snackett's Diary was a present from Jack to Dolores.
