I begin this list by making note of an minor league insert card found in packs of Topps 2016 Pro Debut Baseball. It is from the "Promo Night Uniform" insert set and it celebrates Hawaiian Shirt Night held by the Ogden Raptors -- a Dodgers Rookie League Affiliate. As a man who has more of these shirts than I care to count I couldn't help but be drawn to this card.

There's nothing like a Baseball celebration -- except for a card that highlights a Baseball celebration. Card #9 on my list features Joc Pederson and Adrian Gonzalez with arms entangled on a Topps 2016 Heritage High Numbers "Combo Card" insert card.
