I've seen a couple of old Marvel comics in my collection being credited to someone named "Ricko th' Sicko", and I was curious if the person's real name was known ... but a quick Google search brought up this site, which would seem to indicate that there's actually a character in the Marvel Universe with that name?
So which is it? Was he an artist/writer or a fictitious character?
In the Green Goblin series, Ricko the Sicko was Flash Thompson to Phil Urich's Peter Parker (albeit much more criminal). GG had a 13 issue run that ended right after the Onslaught mess, so that'd be back around what.. '98?
And that sums up all the relevant information I have.
Following up on what lotjx said, the other possibility that would require some sweat equity would be that some conventions might allow you to buy a table so that you could sell directly to comic book fans.
