Share 'Anyone know who is publishing Cometbus?'

Does anyone know who is ultimately responsible for the publishing of Cometbus?   I would like to keep Cometbus in the Click Clack Distro catalog but do not want to order from Microcosm.  I know that Last Gasp and AK Press both are carrying the two most recent issues, but just wanted to see if anyone knew if it was actually Last Gasp who is the publisher?
