In my 20+ years of producing fanworks, this is only the second time I've made art for a gift exchange, and the first was in Harry Potter, so I was reasonably confident that nobody would guess me this round. :D As soon as I was assigned a recipient who only wanted only art and wanted something super in-canon for ACD, I knew I was going to be Wondermark-ing a comic with Sidney Padget illustrations and went from there.
