The Ada Initiative commissioned a portrait of Ada Lovelave to use for their marketing materials and released it under a CC0 license. I lasercut relief and intaglio plates and printed a few different sizes for friends on the lithographic press at NYC Resistor. More photos of the printing process...
In 2014 the Ada Initiative ran a fund raising campaign. I support their mission to provide better resources for women in technology and proudly have their nice stickers on my laptop. You can donate, too, at supportada.org!
