The cards will be available at select retailers starting in mid-summer, Burger King spokeswoman Heather Krasnow said Tuesday.
Financial terms of the agreement weren't disclosed.
Andrews McMeel Publishing, a division of Kansas City-based Andrews McMeel Universal, will design the cards. Recycled Paper Greetings Inc. of Chicago will produce and distribute the cards.
"We're always looking for clever ways for the King to surprise his fans," Russ Klein, Burger King's president of global marketing, strategy and innovation, said in a release. "Now special occasions will be even more memorable thanks to the King."
Will these cards have The King on them? That seems like the smartest move from Burger King. The King has even found his way into Xbox video games.
