Boyd's directory of the District of Columbia
Boyd's directory of the District of Columbia is a city directory published in Washington, D.C. by W.H. Boyd in 1876, listing residents and businesses for the capital's households. Its pictures are numbered wood-engraved diagrams of water closets and sanitary fittings, with plain line work, cutaway views and hatched shading that a designer could use for technical or Victorian plumbing motifs.
