I've sent some originals over to Kiffin along with some stuff that I colored with my graphic markers (that are nearly all dry), the first piece is one I did on paper then took a photo of that original sketch and made a digital version. The original piece was also inked traditionally and sent to Kiffin and Tacki done in nothing but fade-proof archival ink on archival paper, so it really will last forever if taken care of correctly! That second piece is something I doodled on the back of something based on the joke that ended up helping Kiffin and I meet.
