Rare Personal Menu

This is a very rare personal menu from a cruise ship for Valentino, his brother Alberto and few other people. It is dated 1926, I am unsure if this was for a trip Rudy never got to take or a trip from earlier in the year. I know he took a trip back to Italy with Natacha in 1924, but, I am aware of any cruise he took in 1926, maybe someone can clear this up for me, anyway a fantastic piece.
