Don Troiani’s website presents historical artwork and reference material, including an Insignia of Independence Supplement focused on military insignia and related objects. Its catalog covers examples associated with the Royal Navy and British Army, with entries that provide titles, illustrations, materials, dimensions, dates, markings, and reported discovery locations where available. Featured objects include a cast pewter button marked “PN,” a brass cartridge pouch plate bearing a “GR” cypher, and a British cartridge-box badge dated approximately 1750–1760.

Some entries also direct readers to illustrations in a print book, linking the online material with a printed reference. Alphabetical sorting and page navigation help visitors browse the collection and compare individual examples. The content offers a visual resource for readers interested in military artifacts and insignia from the period, while presenting concise details about specific objects.
