I first discovered this type of comic

in the mid 1980's. Shopping in one of the Hispanic corner grocery stores that dotted the more interesting Boston neighborhoods at the time.  
I was shocked to see the lurid painted covers of the Columbian reprints peaking out from the news racks.

Here is the article that I wrote at that time that was in Zontar's Ejecto-Pod #3 (1992):
