This one is just a regular #26-- very little cat value, but check out the date on the cancellation!!

I have a few nice ones in my 1861 collection-- Jan 1, July 4, June 13 (my birthday) and a couple of December 25ths-- now if I could just find that February 29, 1864 or 1868! Also, I'm always on the lookout for April 14 or 15, 1865....pretty important day in US history.
Enjoy!
