New Postage Stamp: Stumblebums

(no image available) I am excited about the new postage stamps: famous stumblebums in US history. I understand that the series will include five different, famous stumblebums dating from the late 19th century to the present day. The images will be nostalgic, slightly comic renditions depicted by a notable contemporary artist, not yet announced. There are rumors that they are being drawn by Daniel Clowes, but that is not confirmed. If anyone has information about the artist, or those being "honored" by the stamps, please comment here!
