From various online sources:
Whitehead and Hoag Co. was founded in Newark, NJ by Benjamin S. Whitehead. As a youth, Whitehead imprinted silk ribbon and button novelties for souvenirs and began experimenting with imprinting on thin sheets of a new material called celluloid. Whitehead went on to perfect the celluloid button, one of the best known and most widely used of all specialty advertising products. In 1891, his company was incorporated as Whitehead and Hoag. (Hoag was Chester R. Hoag.)
Whitehead & Hoag Company ceased business in either 1958 or 1959.
