$20 1988-A FRN PRINTED FOLD ERROR with GREEN + BLACK OVERPRINT on the BACK of NOTE PMG Gem Unc 65EPQ

Prior to receiving the overprints, but after receiving the first two printing processes, the lower right corner of the sheet folded upwards which resulted in the both the green and the black overprint elements appearing on the back design of this Gem printed fold error! A truly spectacular example of an error that's been preserved in pristine condition.
