As you can see there are two Dodger rookie cards available as a part of Topps rookie autograph set: Joc Pederson and Yimi Garcia. I have included two photos for each player: the not normal base auto'd card on the left and an numbered parallel on the right. The Pederson "purple refractor" below is numbered to /250 copies, and the Garcia "blue refractor" is numbered to /150 copies.
Of note, it's nice that Topps decided to use a brand new photo for the Joc Pederson autograph card; whereas, the Yimi Garcia card uses the same pic found in the base set.
