Not trying to spam, I really thought that the 1990s were technically "modern" so I made the same post in the modern topic area. I guess that just shows my age.
In the glorious comics era of the 1990s, Topps broke into the comic market publishing their own books. Among them were the Kirbyverse and the Secret City Saga was a part of that universe. For #0, there were at least four versions.
There was the standard version with a blue background
There was a red version
There was a gold version
And finally a platinum (or silver) edition
Topps Comics had a few titles that were a part of their Kirbyverse. In the first issue (I believe) of each title was a coupon to submit to get your Kirbychrome edition of Secret City saga. I cannot recall if the Kirbychrome was the gold or platinum version. I was completely unaware of the red version until years after the fact and have no idea where it came from. I feel like the platinum was something of a "thank you" or retailer incentive but again, cannot remember at all. Does anyone know about these? In particular, how they were distributed?
