Fox was much older than most of his colleagues, and his comics are noted for their large amount of detail, and stiff "Victorian woodcut" style.
Fox never gave an interview and his only public statement was his own entry for the 1973 edition of Who's Who of American Comics. In it, he names Alex Raymond as his only influence and lists "lithographs, water colors, color woodcuts, oils and etchings" as his other mediums. Fox's last known published work is an advertisement, printed in 1967, for original mail-order glow-in-the-dark posters. Two of his comics appear in the 2010 book Art in Time, a collection of works by "unheralded" comics artists who worked between 1940 and 1980.
