The agreement includes greeting cards, invitations and gift wrap. The range, which launches this month, covers core seasonal events, as well as birthday cards for both children and adults.

"Hallmark has a thorough understanding of The Simpsons brand and has created a range to appeal to all ages and all seasons,” says Carl Lumbard, senior vice president and managing director, FCP. “We're delighted to add Hallmark to our licensee line-up in the year that is a landmark for the brand with the broadcasting of the 500th episode, as well as the fast approaching The Simpsons 25th anniversary in 2014.”
