A VERY FINE AND MAGNIFICENT DESIGN - ALMOST CERTAINLY UNIQUE WITH THE 2c BLACK JACK.
The Northern craze for patriotic envelopes had waned by the time the 2c stamp was issued in the summer of 1863. Use of the 2c Black Jack on patriotic cover is rare - limited both by the time period and applicable postal rates for this stamp. Use from the West, where patriotics were quite scarce, is extremely rare. This example is remarkable for its design, origin and franking - a triple-rarity factor that is probably unique. Ex Jessup
