A week or so ago I finished up the 8 issue original run of OMAC by Jack Kirby, and ordered an OMAC action figure.
Comes with a Brother Eye pin!
As I waited for the figure to arrive, I did some web browsing to see if/when OMAC appeared in any comic prior to the relatively recent Batman/Brother Eye story line.
Somehow I missed out on a prestige format 4-issue mini-series by none other than John Byrne, one of my all time favorite comic artists/writers.
I managed to find the series on eBay for about half the original cover price per issue.
