The result is a number of very local , slightly wonky exhibits dedicated to New York City : a retrospective on Daniel Patrick Moynihan ; a showing of works by Samuel Gottscho , a little-known photographer who shot New York buildings in the 30 's ; and the Koch show , in which museum visitors are greeted by a life-size cardboard cutout of the extroverted mayor and graphs illustrating New York 's 70 's - era budgets .
