Very nice example. I love the large size, state obsoletes. This is a popular American Bank Note Co., N.Y. & N.O. engraved note. At top center, under the title, a man on a mule leads the animals in pulling a wagon. The Colonel Haynes portrait in an oval is at top left. At the lower right, a field hand picks cotton. The note has a handsome vermillion tint plate added with an outlined white FIFTY on a horizontal die. Edited to add; The Heritage description is being a bit politically correct describing the "field hand picks cotton" ....we all know back then they were known as slaves.
Thanks for neat comments, I will try to post more of my material. I also collect Worldwide AV coinage 650BC-present.
