The original stamps were issued on July 30, 1934, in sheets of two panes with a center line terminating in arrows at top and bottom. They are perforated and gummed. The reprint of the special printing (Scott #760), ungummed and imperforate, was issued on March 15, 1935.
This example of the original special printing bears one inscription:
“To Betty, Ann and James Farley from their [the] Dad./ This is the second sheet of the five cent Yellowstone Stamps issued July 23, 1934/ James A. Farley, Postmaster General”
On the bottom selvage is the autograph “Franklin D Roosevelt”.
Note the error in the Farley inscription. This early sheet was printed on July 23, 1934. The first day of issue was seven days later—July 30, 1934.
