The Postal Service had become increasingly lax about employing purple for 3¢ stamps, and after the war, departures from that color in double-width commemoratives veritably became the rule rather than the exception (although U. P. U. colors and purple for 3¢ stamps would continue to be used in the definitive issues of the next decades). Beginning in 1948, Congressional Representatives and Senators began to push the Post Office for stamps proposed by constituents, leading to a relative flood of stamps honoring obscure persons and organizations. Stamp issue did not again become well regulated until the formation of the Citizens' Stamp Advisory Committee (CSAC) in 1957.
