According to Standards Manual:

New York City Transit Authority: Objects contains over 400 artifacts related to the New York City Subway, collected and documented by photographer Brian Kelley.

Kelley started collecting MTA MetroCards in 2011, and he quickly became fascinated by other Subway-related objects. This catalogue is the first of its kind presenting a previously uncollated archive of ephemera dating back to the 1850s.

The Roosevelt Island Historical Society (RIHS) and New York Public Library are hosting a free virtual Zoom lecture presentation by Mr Kelley, author of the book.

According to the New York Public Library:

The Roosevelt Island Historical Society and the New York Public Library are
proud to host Brian Kelley and his presentation of his Photo-book “New York
City Transit Authority: Objects”.

Brian Kelley (b. 1988) moved to New York City in 2006 and received his BFA in photography from the School of Visual Arts. Kelleys work resists the hurried march of consumerist modernity, seeking to halt the cyclical emptiness of our material lives to capture a sense of culture at the end of history.

A mixed-media approach has allowed him to pursue artwork with disruptive capacitiesexhaustive research, slow & meditative composition, and the repurposing of photographic mediumsall employed to reveal the artifacts left behind by the precession of simulacra. Kelley was born in Horseheads, NY and currently lives in Lumberland, NY
