This is a letter by Wallace Edmonds Conkling
(1896-1979), a prominent American bishop of
the Episcopal Church. Conkling served as the
seventh bishop of the Episcopal Diocese of
Chicago from 1941 to 1953.
The signed program was for a Sunday morning
prayer and sermon. It is dated January 20, 1946.
The service was held at The Cathedral of the
Incarnation in Garden City, New York. Bishop
Conkling was a special guest at that service,
and the fourth page of the program includes
a biography of him (see photos).
This program was originally part of the collection
of a man named Clifford John Benfield (1924-2018),
who began collecting the autographs of members
of the Episcopal clergy when he was a choir boy.
(NOTE: I now own many of those autographs,
and will be listing them for sale on ebay soon.)
Unfolded, the program is about 11.5" by 9".
