William Hubert Miller Jr. (September 1932 – November 4, 1988), of New York City, was an aerophilatelist who published philatelic literature on the subject.
As a result of his studies, Miller wrote articles in the philatelic press on various aspects of aerophilately.
In addition he served in a number of positions at the Collectors Club of New York.
According to the Scott Postage Stamp Catalog, air mail postage stamps were issued by postal authorities during the first half of the 20th century and discontinued during the decades after World War II.
Miller’s philatelic literature helps illustrate this period of aerophilately within the field of philately.
