Bid and specification for the furnishing and erection of an Edison incandescent electric light plant for the Allegheny County Court House and jail, Pittsburgh, Pa....
A bid and specification from 1887 issued by the Edison United Manufacturing Company, offering to furnish and erect an Edison incandescent electric light plant for the Allegheny County Court House and jail in Pittsburgh, Pennsylvania. The only picture is a blank page marker with a blue circular mark, so it offers nothing to draw on beyond a sparse grey and blue layout.
