This is one of the notes where the vignette escaped the clutches of the BEP. The eagle was engraved by the National Bank Note Co. Around 1877, the Bureau of Engraving and Printing brought all currency printing in house. The dies, rolls, and printing plates that commercial security printers had used for federal currency were all supposed to be turned over to the Bureau.
BUT, this vignette had a copyright -- and you can see the long-form version of this in a ribbon of microtext under the eagle. (You can actually see remnants of this text on the $100 note.) So National BNC did not turn in this die and it was used on several later stocks and bonds, as well as a souvenir card.
