This Artmaster cacheted First Day Cover marks the January 5, 1968, issuance of the 10¢ U.S. Air Mail stamp in San Francisco, California. The cover bears the red 10¢ booklet stamp depicting a stylized pyramid of envelopes and carries the official first-day cancel.
The stamp updated domestic airmail rates at a time when jet service had dramatically expanded U.S. postal aviation. Its simple, bold design was intended for high-visibility use on airmail envelopes during the final years before airmail as a separate class was phased out.
The Artmaster cachet features a dramatic bald eagle perched on a continental U.S. map with Alaska and Hawaii insets, emphasizing nationwide airmail connectivity. The “Booklet” inscription notes the stamp’s booklet-pane origin.
A fine addition for collectors of Artmaster cachets, airmail postal history, or 1960s U.S. definitives, this cover is in fresh condition with a crisp strike and attractive engraving.
