Long ago I posted an interview with machine-free (hand-poked) tattoo artist and pioneer Boff Konkerz (read it here), but at that point he was better known for smaller pieces. Boff told me back then that he figured hand-poked tattoos took about three times as long as “normal” tattoos in general, so as you can imagine doing a full backpiece is quite a commitment. Boff is based at King of Hearts in London, but travels extensively across the UK and Europe — follow his plans or get in touch via fb/RoadmapsForTheSoul.
Here are a few backpieces, epics of machine-free tattooing, that Boff has done. The first one by the way you may recognize elements of — it is based on Last Embrace by Laurie Lipton (although the motif of embracing skeletons is not an unusual one).
