The venture between Hallmark and Sprint is the first product marrying greeting cards with the fast-growing category of prepaid long-distance calling cards. Hallmark began testing the product in five cities last fall.
Each $5.95 card offers 10 minutes of prepaid long-distance calling anywhere in the U.S., Puerto Rico and the Virgin Islands via a toll-free Sprint number. The card includes a code authorizing the free calling.
The 24-card line hasn't yet been advertised, said Hallmark spokesmen. Leo Burnett USA, Chicago, is Hallmark's agency.
