First but not last attempt with sketch cards, I find it extremely difficult to draw this small but thought these tured out okay. First I tried straight up pencil on bristol...no luck... then acrylics on canvas... even worse luck... then finally the standard pastels on velour paper which, then I fixed a sheet or Bristol to the back for support... then cut them into cards. Trying to see what the market is for Big Lebowki sketch cards ha ha.. I would like to do more cards of characters you might not see anyone else doing. Anyway I popped these up on Ebay, here is the link for the Dude card:[link]
Also thanks to a couple artist here I talked with about sketch cards, I appreciate it... Raats, the Aphex, Icarus and KartK.
