The 1869 Pictorial Issue is a series of definitive United States postage stamps released during the first weeks of the Grant administration. Ten types of stamp in denominations between one cent and ninety cents were initially offered in the series, with eight of these introduced on March 19 and 20, 1869 and the two greatest values being distributed somewhat later. During May, however, the Post Office began distributing a revised version of the 15-cent stamp, in which the original, poorly aligned frame had been modified ; and collectors consider this eleventh stamp an integral part of the Pictorial Issue.
