Joe_G.You've got a problem John, have you ever passed on a Corcoran before?
I have a minute to kill, so here's a little history.
Corcoran has two poses originally issued in 1887 within the common leading "0" numbered series with Indianapolis. Both poses were re-issued a 2nd time in 1887 under the type 2 "0" numbered series (card number, name, position, and team in script at bottom with smaller restyled OJ banner/box). Then a third variation with his new London team surfaced in 1888 (again both poses).
So John, you not only have all 6 variations (as shown in your avatar), but you are collecting dups. How many Corcoran cards do you have? Are you finding the "a" variation is easier than "b" is easier than "c"?
Happy collecting?
