Paul now has his own publishing imprint called Cafe Digital, and you can get the Little White Mouse collections from there. He will also be soliciting them through Diamond Distributing (Hmmmm... maybe I'd better get him together with Khepri.com ), so your local comics store might carry them too. If they're savvy that is.
Paul is one of the coolest guys on the planet, and his work is criminally overlooked by comics readers. Little White Mouse is suitable for all ages, and it's a fantastic read. Buy yourself an early Christmas present. Hell, buy your best friend one too. They'll thank you for it, trust me.
