Who is the hidden man on the 20 bill?

Answer 1

The "hidden man" on the $20 bill refers to the image of Andrew Jackson, the seventh President of the United States, who appears prominently on the front. However, in certain light and under specific conditions, a ghostly image or watermark of a man, often referred to as the "hidden man," can be perceived, though this is more of an optical illusion than a distinct figure. This phenomenon is part of the intricate security features designed to prevent counterfeiting.
