The One-cent Prexie
Transient second class use
The transient second class rate was available for mailing newspapers or periodicals by other than a publisher or registered news agent. A rate of one cent per two ounces, total weight to be less than or equal to eight ounces, was in effect from July 1, 1928 until April 1, 1952.
A small Bulletin of the New York Academy of Sciences was sent for one cent as second class matter.
