Whiteboard
Albert Stallion invented whiteboards while working at Alliance in the 1960s. Alliance (now known as PolyVision) produced enameled steel for architectural cladding, but Stallion noted it could also potentially be used as a writing surface. Stallion later left Alliance to form his own whiteboard production company, MagiBoards.
Scratchboard
Modern scraperboard originated in the 19th century in Britain and France. As printing methods developed, scraperboard became a popular medium for reproduction because it replaced wood, metal and linoleum engraving. It allowed for a fine line appearance that could be photographically reduced for reproduction without losing quality. It was most effective and expeditious for use in single-color book and newspaper printing. From the 1930s to 1950s, it was one of the preferred techniques for medical, scientific and product illustration. During that time period, Virgil Finlay made very detailed illustrations, often combining scraperboard methods with traditional pen & ink techniques, and producing highly detailed artworks. In more recent years, it has made a comeback as an appealing medium for editorial illustrators of magazines, ads, graphic novels, and one of a kind pieces of fine art displayed in galleries and museums internationally.
