2019 Topps Baseball - London Series
A third set of cards being issued to commemorate the MLB game at West Ham United's London Stadium. The cards have the same design as the 2019 Topps Baseball series but have a prominent "London Series" logo on the front and are a UK exclusive, with the box costing £6.00 on the Topps UK website. The boxed set consists of just 21 cards and there are no inserts or parallel cards. There are 9 cards for each of the two team - Boston Red Sox and New York Yankess and three info cards round out the set. Topps UK haven't yet provided a checklist.
