The Anglers' Club of New York appears to have been founded in 1905.  It is an exclusive social club whose members are united by their love of fly fishing.  Membership is strictly capped and by invitation only. One story I found recounted an obituary stating that the deceased had spent three decades on the waiting list for club membership.

The circular medal measures 63.7mm and was struck in bronze by the Medallic Art Company of New York. No mintage is reported.

Many thanks to the Yale University Art Gallery for making this medal available to me for research.
