Polk's presidential franks are relatively scarce. According to Hart's research on this cover, it left Washington a few days before June 20, probably in a diplomatic pouch, on the American steamship Hermann, which made regular transatlantic voyages. In London it was placed in the British mail, sent to Aaachen and from thence to Russia, collect.
