The first time i have see the legend Pendleton Ward was at CSSSA in 2010. The second time you see here is at a art gallery in 2011. He was really nice and he drew me Jake the Dog on my sketch book. The little girl standing next to me is my sister. She is a bigger fan of his work then i am.
In case you don't know who Pendleton Ward is, then here is his Wiki info.
He is an American animator, screenwriter and producer who works for Cartoon Network Studios, and Frederator Studios. He created the three time Emmy-nominated Adventure Time (2010) and Bravest Warriors (2012). Ward is a graduate of the CalArts Animation Program.
