Ian Jepson is an Illustrator/Poster Designer from Cape Town, South Africa and sent me a message about a couple of cool looking Halloween posters he just finished.
He just released his first ever screen prints with The Prince Ink Co. in Virginia. One is titled Be Afraid and the other Grim Reaps
They're both 18" x 24" 5 color prints on Cougar 100# stock in an edition of only 25, and they have a layer of glow-in-the-dark ink too!
They're available here: http://shop.princeink.com/ and he posted a bunch of process pictures to his Behance page here: http://www.behance.net/ianjepson .
