The public heartily disliked the 1869 Pictorial Issue, and this accounts for its short lifespan. Difficulties, mentioned earlier, included the stamps' size and the poor quality of the gum. The conflict between the Butler & Carpenter firm of Philadelphia and the National Bank Note Company over the contract award had not been resolved when Postmaster General John Creswell assumed his position in 1869. This offered him an opportunity to change the order for the 1869 Issue, but he let the order stand, not anticipating the problems the Pictorial Issue would face when released in the spring of 1869.

In 1861 Congress authorized the United States government to finance the Civil War with its own paper money rather than that issued by private banks. Congress also authorized the creation of the Bureau of Engraving and Printing (BEP) as a division of the Treasury Department.

The Bureau began operations on August 29, 1862, its initial functions being signing, separating, and trimming sheets of the Treasury's privately-printed Demand Notes. Over time, the Bureau assumed more of the work of engraving and printing, producing fractional currency, revenue stamps, government obligations, and other security documents for many federal agencies. The Bureau was the sole producer of all U.S. paper currency by 1877.

The United States enjoyed its last full year of peace in 1940. The nation's 44,024 post offices handled almost 27.75 billion pieces of mail that year, and the Famous Americans Issue became the first commemorative series of the period. It would be the first large commemorative series since the Columbian Exposition Issue to not include an American president as a stamp subject. Instead, it would incorporate the first commemorative stamp to honor an African-American, the 10-cent Booker T. Washington.
