The Act of March 3rd, 1863, establishing a two cent rate for drop letters and abolishing the carrier's fee, made the issue of a two cent stamped envelope and wrapper imperative. The new die appeared about the middle of 1863, and is a miserable caricature of Jackson, facing the left. The inscriptions are "U. S. POSTAGE" above, and "TWO CENTS" below, in colorless, block letters. We may as well state at once that in the next year (1864), the design, though retaining Jackson's bust, was altered, and the upper inscription changed to read "U. S. POST."
