Gary, glad to see your enthusiasm, you have a nice start on McGuire. Jay (oldjudge) has helped many of us over the years, his objection stemmed from your passion declaration which fell short of researching a number of posts or the book you are now familiar with.

Deacon McGuire is an interesting player to collect. While you are complete at 4 different poses, he was issued and re-issued cards from 1887 to 1889 such that he has 17 different variations currently checklisted (may be others out there as well). Five of the listed variants will be tough including Gypsy Queens (Es), 1888 re-issues (Fa & Fb), and cabinet (G). Most of the other twelve are possible given enough time and patience (the 1887 long numbered cards (type A & B) and the 1889 (Fc) re-issues).
