Carl William (Bill) Polvogt, Jr was a well known commercial and cartoon artist in the Golden, Colorado area through the 70's and 80's. He died in 1993. Was a friend of one of the original "Royal Products" guys and was hired to be responsible for all of the "conceptual art'' for Royal (America) products, including insert artwork and posters, box and labeling artwork, as well as any artwork on plans and manuals that were isometric or angle views. However, he had nothing to do with planviews, design, construction drawings or development.
