Frustrated that the US Treasury Department is walking back plans to replace Andrew Jackson on the front of the $20 bill with Harriet Tubman, Dano Wall created a 3D-printedstamp that can be used to transform Jacksons into Tubmans on the twenties in your pocketbook.

If you have access to a 3D printer (perhaps at your local library or you can also use a online 3D printing service), you can download the print files at Thingiverse and makeyour own stamp for use at home.
