I have recently acquired these beauties from Samurai Jack. The internet can be a magical place sometimes...
The precision with which these were painted is stunning. They are definitely hand done, but with an almost machine-like accuracy and control. Amazing to see in person! Btw, if anyone knows whether it was Scott Wills or Jenny Gase-Baker that did them, I'd love to know!
EDIT: The top was likely done overseas and the bottom one was done by Jenny herself! Thanks to Chris and Jenny for confirming!
EDIT EDIT: See post above for Scott's clarification.
