From Linn’s Stamp News by Charles Snee:

Katharine Graham, the formidable owner and president of the Washington Post Co. who served for almost 30 years as publisher of the organization’s flagship newspaper, the Washington Post, will be celebrated on a new United States forever stamp in the Distinguished Americans definitive series.

The nondenominated (78¢) forever stamp will be issued June 14 in Washington, D.C. The “Two Ounce” inscription indicates the stamp will satisfy the 2-ounce first-class letter rate regardless of future rate increases.
