The shop of Joseph, John, Philodogus and Thomas Loud was located at 144 Chestnut Street where they sold a variety of high quality musical instruments to local and foreign markets. The partnership advertised for merchant-steamers to ship pianos to the West Indies and South America; prior to his partnership in Philadelphia, Thomas Loud advertised the sale of pianos in Baltimore, again attesting the fluidity of goods between those cities.

A similar Loud Brothers piano was sold in these Rooms on June 2, 1990, Lot 248, and another example is illustrated in Marshall B. Davidson and Elizabeth Stillinger, The American Wing: the Metropolitan Museum of Art, (New York, 1985), p. 160, fig. 248.
