If that is true, Khanna could end up making a fortune if matchboxes go extinct. “This is just a pursuit with no intention to monetise,” he says with a glint. For the uninitiated, this is quite different from collecting stamps or maps, which calls for greater attention and even some running costs. In contrast, Khanna hasn’t paid more than €2 for a box. “The only hitch is they get a little moist during the rains,” he points out. The best place to look for a matchbox is the hotel room. Khanna himself confesses to pinching quite a few and says there are antique shops in Europe that sell very affordable matchboxes. “In the past, airlines like Pan Am gave matchboxes away. That never takes place today,” he says.
