1909 HUDSON-FULTON CELEBRATION SCOTT #372-373

  A 1909 celebration remembered two different Hudson River events: in 1609 Henry Hudson discovered the river in his sailing ship, the Half Moon; and in 1807, Robert Fulton proved that his steamship, the Clermont, did indeed work. The Clermont became the first successful navigation with a steam powered ship. The first stamp has perforations the second stamp is not perforated.
 Interesting fact--these stamps picture both the Hudson and the Fulton ships, although the two existed 200 years apart.(Artistic License).
