The stamp depicts Diana, the huntress and goddess of fertility, reaching behind her head to pull an arrow from her quiver to fend off an enemy, in this case, breast cancer. The image reflects the same position that a woman assumes for a breast self-exam and mammography.

Since 1998, the stamp has raised over $65 million for breast cancer research.

The U.S. Postal Service currently has three 45-cent fundraising or "semi-postal" stamps available for purchase at Post Offices, online at The Postal Store, and by toll-free phone order at 1 800 STAMP-24.

The price of a semi-postal pays for the First-Class single-piece postage rate in effect at the time of purchase plus an amount to fund causes that the Postal Service determines to be in the national public interest and appropriate. By law, revenue from sales (minus postage and the reasonable costs of the Postal Service) is to be transferred to a selected executive agency or agencies.

The Breast Cancer Research semi-postal was issued on July 29, 1998, at a first day ceremony held in the White House. It was the first semi-postal in U.S. history.

To date, the stamp has raised nearly $55 million for breast cancer research. By law, 70 percent of the net amount raised is given to the National Institutes of Health and 30 percent is given to the Medical Research Program at the Department of Defense.

Designed by Ethel Kessler of Bethesda, MD, the stamp features the phrases, "Fund the Fight" and "Find a Cure" and an illustration of a mythical "goddess of the hunt" by Whitney Sherman of Baltimore.
