The Farley Special Printing Series

Issued by Postmaster General Farley as imperforate sheets for the benefit of President Roosevelt's political croonies, the issue was made available to the general collecting public following a congressional outcry and accompanying oversite investigations.

All were issued without gum and were on sale only at the Philatelic Agency in Washington, D.C. from March 15 through June 15, 1935. The set can be distinguished from the National Parks Issue of 1934 as all were issued imperforate, but otherwise from the same plates.
