A quick follow-up about Hal Chase. Chase also has 6 cards in the set, Portrait, Trophy, and Throwing for the White Sox and Buffalo. His Chicago cards are a little more difficult to find, but not by much. What's interesting about this, is that it suggests that they produced more cards in 1914, than 1915 and 1916. This bio includes the story of Chase playing part of 1914 with Chicago, before moving to Buffalo in 1914-1915. As Ted pointed out earlier in the thread, Chase should have T213-2's from 1916 showing him on Cincy, but none are known.
