Weinman's work as an architectural sculptor can be found on the Wisconsin, Missouri, and Louisiana state capitols. He became the sculptor of choice for the architecture firm McKim, Mead, and White and designed sculpture for their Manhattan Municipal Building, Madison Square Presbyterian Church (completed 1906 and demolished 1919), Prison Ship Martyrs' Monument, and Pennsylvania Railroad Station (completed 1910 and demolished 1963), all in New York City. A photograph of one of his angels, Day, in a landfill in New Jersey is one of the saddest reminders of the destruction of Penn Station in 1963, but two of his eagles were retained as trophies outside the entrance to the new subterranean Penn Station.One is illustrated in Walsh, Kevin. Forgotten New York: The Ultimate Urban Explorer's Guide to All Five Boroughs, 2006:169: "Others can be found in Kings Point and Hicksville and as far away as Philadelphia". Elsewhere he created the dramatic frieze on the Elks National Veterans Memorial in Chicago and executed sculpture for the Post Office Department Building, the Jefferson Memorial, and the interior of the U.S. Supreme Court, all in Washington, D.C.
