I bumbled on the keyboard and wiped out the sidebar we used to have here that offered quick links to all the digital comics collections offered here. As said in the sidebar, please contact Paul Tumey if you would like to purchase his two fine volumes of Jack Cole's MIDNIGHT comic-book series (and if you don't have them, you need them).
Here are the purchase links for ROBOTMAN Volumes 2 and 3. They're $2.99 USD each. See elsewhere on this blog for descriptions and images from these e-books, which have been purchased by many happy customers.
