Great info and research Jason! I don't have any cards of these players (maybe a w514 Ad Luque), but I will share a short story about Jose Acosta.

Acosta pitched briefly for the 1917 Vancouver Beavers in the Northwestern League. I say briefly since the Northwestern League's 1917 season was shortened by United Stated entry into World War I. Acosta was not the only player on the team to "break the color barrier" that season. A "dark-skinned" Chinese Hawaiian shortstop Vernon Ayau was traded amongst Seattle Giants, Tacoma Tigers, and finally landed on the Vancouver Beavers roster. I believe Ayau moved to New Jersey in 1918. A Cuban pitcher and Hawaiian shortstop integrating a Pacific Northwest baseball league, the game was far more global that many know prior to WW1....
