Are there any good pictures of MRS Andrew Jackson ?

Mrs Washington was on the back of the 1896 "Educational Series" $1 bill called "History Instructing Youth.

Yes, there is at least one painting of Rachel Donelson Jackson--I have a refrigerator magnet (bought at the Hermitage) with a reproduction of the painting.

If they want a Native American, I would vote for Pocahontas (as depicted during or soon after her lifetime, not the Disney rendition). But because the current image is Andrew Jackson, I think John Quincy Adams, Henry Clay, John C. Calhoun, or Nicholas Biddle would be better replacements.
