Vipin Bharti, who owns Card Gallery in Chawri Bazar, sells cards that cost as low as Rs.1 per card. The expensive ones range from Rs.200 to Rs.500. His company makes changes in designs twice a year.
"We change designs after every six months. Sometimes, we use craft paper with digital printing or design it in a book form with pictures of Lord Krishna and Radha," Bharti told IANS.
