Over one hundred members of the New Jersey Construction Trades Council signed this memorial sign thanking rescue workers and sending condolences to those who had lost family members. Electricians, laborers, pipefitters, ironworkers, carpenters, operating engineers and boilermakers are among the trades represented on the list, which was at Battery Park when the photograph was taken, but subsequently moved to the Ground Zero area.

Photograph taken September 28, 2001 by Martha Cooper. View more photographs of the spontaneous shrines that appeared after September 11, 2001 in the Labor Arts exhibit “Missing.”
