By Alexander Haimann, Collections SpecialistToday, February 9, 2010 is my 24th birthday. As someone with a lifelong passion for stamps and postal history, I am fascinated by historical dates. February 9th is a date with particular importance to me for obvious reasons. I also share this birthday with America's 9th president, William Henry Harrison, who died one month after assuming the Presidency in 1841. Whenever I am looking at a postal history object with a date attached to it (usually envelopes/covers displaying a postmark), I can't help but notice when the date is February 9th, regardless of the year. This blog post showcases a few intriguing pieces of American postal history all connected by their February 9th postmarks.
