In the meantime, here's kind of a neat thing that I stumbled into today, even though it was actually posted on the Argo Comics Facebook group back in April. The cover to the 17th issue was provided by Michael T. Gilbert, the gentleman who revived Mr. Monster in the mid-80's.
Argo has a couple of Canadian characters of their own, but that I know of they haven't appeared recently. I believe the plan was for them to be included in the Argo anthology book, but while issues of Argo 5 have been released with some regularity, there's hasn't been an anthology title in some time. Still, we'll keep an ear to the ground.
