United States Post Office "100 Years of Progress of Women" 1948

UNITED STATES POST OFFICE on 19 July 1948 issued a First Day Cover commemorating "100 Years of Progress of Women" from 1848 to 1948. Shown here is a block of four 3-cent United States postage stamps, celebrating  this centenary. The cancelation postmarked on this envelope originated from Seneca Falls, N.Y. The stamps featured portraits of three prominent figures in the women's rights movement: Elizabeth Cady Stanton, Carrie Chapman Catt, and Lucretia Mott.

The year 1848 marked the Seneca Falls Convention, the first women's rights convention held in the United States, where Elizabeth Cady Stanton was a key organiser.

Carrie Chapman Catt was a leader in the women's suffrage movement, who played a crucial role in securing the passage of the 19th Amendment, which granted women the right to vote.

Lucretia Mott was an abolitionist and a women's rights advocate, also instrumental in organising the Seneca Falls Convention.

The cachet on the envelope depicted portraits of Elizabeth Cady Stanton, Carrie Chapman Catt and Lucretia Mott under a banner reading, "Commemorating  100th Anniversary of the First Woman's Rights Convention held July 19-20, 1848, at Seneca Falls,. N.Y.
