Inkworks has come up with a particularly nefarious way to tantalize collectors on Free Comic Book Day this weekend -- they're distributing free promo cards featuring the Justice League by region.  Five of the seven promo cards will be made available in five regions of the United States, the sixth will be made available through retailers outside the U.S., and the seventh is being distributed through the Inkworks Website. 

 

Inkworks' Justice League Premium Trading Cards, based on the Cartoon Network series, will be released June 25th.   It's an 81-card set in 7-card packs, 36-pack boxes.  Chase cards include seven lenticular cards plus sketch cards by Justice League animation artists.
