The USPS Souvenir Page Program began in early 1972. The Postal Service had observed the interest in Stamp Poster with First Day Cancels and decided to begin a program of their own. They started with the Family Planning Stamp in March 1972. This Souvenir Page (#72-0) was sold at the ASDA Stamp Show in New York City. It was sold only at the Show in Madison Square Garden and at the Main New York City Post office across 8th Avenue. Subscription service to collectors began with National Park Series in the same month. Four Souvenir Pages were included in the first wave (#72-1, 72-2, 72-3, and 72-4). About 2,000 of the Family Planning Souvenir Page were Sold and around 10,000 of the first four subscription pages. The Family Planning Page is 'rare' and the first Subscription four are 'scarce' This series has now reached over 1000 major types, and included enough variety to keep a collector busy for years. Coil plate number and booklet pane collectors, for example, have many numbers to hunt.

All pages are 8 x 10-1/2 inches.
