Larry Flynt, Hustler Magazine offers $1 million for information on Mitt Romney's tax returns

(CNN) - A magazine known for its sexually explicit material is offering a reward of $1 million dollars for a different type of bare-all expose.

The publisher of Hustler magazine, Larry Flynt, is offering the sum for the skinny on GOP presidential candidate Mitt Romney's financials, the magazine announced.

It is taking out full-page advertisements in two newspapers - The Washington Post on Sunday, and USA Today on Tuesday - "offering up to a million dollars in cash for documented evidence concerning Republican Presidential candidate Mitt Romney's unreleased tax returns and/or details of his offshore assets, bank accounts and business partnerships," a press release from the magazine read.

Flynt's announcement could be seen as either an attempt to keep the issue of Romney's financial documents alive or put himself - and his magazine - in headlines.

Romney has released his tax returns for 2010 and an estimate of his 2011 tax liability, but has repeatedly said he would not release additional years, saying it would be fodder for Democrats to criticize him.

In recent months, various political figures, including some Republicans, have called for more transparency from Romney.

Earlier in the week, an anonymous online poster claimed it was holding stolen tax documents belonging to Romney ransom for $1 million in an internet currency. Should the sum not be paid by later this month, the posting said a key to unlock the documents would be released publicly, while the financial firm from which the documents were allegedly stolen said there is "no evidence of unauthorized access to our data."
