What do you win when you buy a portrait with your extra deja vu wins in world of flavor?

The portrait of Cesar will allow you to use him for your game profile avatar. To see your list of avatar options, tap on your current picture, then tap on the pencil above your picture. Memoir portraits are all the way on the right side. It is always free to change your avatar.

Note, this is different than the Cesar's Reminder, also in the Deja Vu Store, which will fill one missing snippet of your choice. After this card is purchased, it will be found on the bottom left of your Memoirs book.
