Marvel Fans don’t look at this as advertising. It’s more of a giveaway. It took me 1.5 years to build the largest mobile database of key issues and Im giving it away for free on the iTunes Store and Google Play. You can view over 7,000 key issues with price guidance, catalog what you own and build a wish list of what you want. No ads. No freemiums. No profit. Check it out and let me know what you think. Thanks! -Nick
