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.
Ginny Lloyd
As a visiting artist in 1981, Lloyd worked at the Image Resource Center in Cleveland to create the first color Xerox billboard art assisted by the Cleveland Institute of Art printmaking faculty, Alexander Aitken. This was her third copy art billboard exploring the use of Xerox copiers in large formats. She continued to produce billboards nationally participating in The Art Billboard Project documented in her book "Billboard Art". She currently advises artists on the art of making billboards.
