To further indicate the complex contiguity and the chance simultaneity of metropolitan experience, Metzker arranged twelve prints from the film rolls into two panels that float one above the other. These six-part strophic variations have a strong graphic beat and complex internal repeats informed by the artist's keen interest in kinetic sculpture and percussive movement.
"Port Authority" is one of the last fifteen unique composites Metzker made between 1964 and 1967. In line with contemporary developments in Conceptual, Pop, machine, Op, and performance art, these large wall-sized works uncannily merge the crucial artistic issues of the 1960s. Their technical innovation and intellectual integrity remain unsurpassed, providing a precocious challenge to current photographic practice.
