I almost forgot all about this set.
Featured here are the four Dodger prospects found in packs of 2015 Leaf Ultimate Draft Baseball. They include Jose De Leon, Julio Urias, Walker Buehler and Yadier Alvaraz. Go here for a complete checklist.
Since Leaf does not have an MLB license none of these cards have team logos on them, so the photos look a bit odd. The exception to this is the Yadier Alvarez card that shows him in a "IPL" uniform. IPL is the International Prospect League and they put together showcase events for unsigned Latin American ballplayers.
