Robert Wornum &amp; Sons exhibited cottage and grand pianos as well as their "folding" square at the 1862 International Exhibition in London, receiving a medal for "novelty of invention in piano"—one of almost seventy piano manufacturers to receive a prize medal including Broadwood, L. Boesendorfer of Vienna, Pleyel, Wolff &amp; Cie, Paris, and Steinway &amp; Sons, New York. They exhibited a piccolo upright, as well as moderately priced downstriking grand and square pianos without metal bracings at the 1867 Universal Exposition in Paris, where they were awarded a bronze medal, at the same level as J. Brinsmead of London, J. Promberger, Vienna, and Hornung &amp; Moeller, Copenhagen, among others, but below the level of most of the manufacturers judged to be their equals in previous exhibitions.
