$1 1969-D FRN AUTOGRAPH on ERROR NOTE : Banuelos Signature on Offset Error Ch CU

Romana Acosta Bañuelos was the 34th Treasurer of the United States. Appointed by President Richard Nixon on September 20, 1971, she served from December 17, 1971, to February 14, 1974. Born in Arizona into a poor family of Mexican immigrants, Acosta was deported with her parents during the Depression. 

Her signature appears directly above the engraved signature, but the exciting surprise is on the back! When we flip the note over, we notice there's a partial  face to back offset error in the back right margin where the design frame is present! Super exciting and elusive opportunity to secure an error autograph!
