In 1908, the Post Office Department issued a new set of Definitive (Regular Issue) stamps. Denominations included 1¢, 2¢, 3¢, 4¢, 5¢, 6¢, 8¢, 10¢, 13¢, 15¢, 50¢ and $1. The 1¢ stamp pictures Benjamin Franklin, with all others featuring a profile of George Washington.

The border designs are identical, with a much cleaner and more modern look than previous issues. The uniformity and simpler design were initiated in order to make preparation work easier and to extend the life of the printing plates.

The 1908-09 designs remained in use for several years, with numerous varieties in terms of perforations and watermarks. U.S. #350 is printed on double line watermarked paper and perforated 12 horizontally.
