Albums for First Day Covers, #10 Envelopes and all types and sizes of Postal Stationary.

A First Day Cover (FDC) is an envelope or card bearing a stamp which is cancelled on the day the stamp is initially placed on sale by the postal authorities. A FDC with the Snowy Egret stamp (A) is shown with a New York, NY, First Day of Issue cancel (B) and a cachet (C), pronounced ka-shay, which compliments or tells us something about the stamp.

Although most U.S. stamps are released nationwide on the first day, the U.S. Postal Service (USPS) will designate a single city as the “official” first day city. (Sometimes multiple cities are designated as “official.”) The location is usually appropriate to the subject of the stamp and will be the only place where the “First Day of Issue” postmark is used.
