The good news is that because of this I was browsing usps.gov for stamp options and discovered this beauty, perfect for our Hallowedding:
That's right, it's Mr. Poe himself! The site says:
On January 16, 2009, in Richmond, Virginia, the Postal Service™ issued a 42–cent, Edgar Allan Poe commemorative stamp, designed by Carl T. Herrman, Carlsbad, California.
In 2009, the U.S. Postal Service® commemorates the 200th anniversary of the birth of Edgar Allan Poe, one of America’s most extraordinary poets and fiction writers. For more than a century and a half, Poe and his works have been praised by admirers around the world.
I think it strikes just the right note: spooky, without being gory, plus I like the added literary connotation. I hope they offer them in the 44-cent stamp, but with my luck, I'll end up with hearts and flowers.
