I made the drawings about 4 years ago, in December 2008. They're all just marker on 21cm x 15cm, acid free 110gsm cartridge paper.
All three drawings are of somebody donating blood.
I'd forgotten all about it until I saw these drawings again, but yeah, it was pretty funny laying back on the Upwey Community Centre stretcher, looking at the other people laying back on the other Upwey Community Centre stretchers, and scribbling away with my right arm while the needle sucked blood out of my left.
(PS. Make me an offer I can't refuse if you're interested in buying these drawings, I'd be happy to sign the back of them in blood. Or, if for some strange reason you'd rather I didn't bleed on them, I guess I could just use pencil).
