 Exhibitors at the Dallas Card Show were taking down their booth Sunday when a man approached the vendor for legacy cards and started showing him pictures on his phone. The distraction allowed an accomplice to swipe a case filled with baseball cards, including the Holy Grail among collectors, the 1952 Topps Mickey Mantle rookie card. Six of them. So hopefully they can locate those cards, very valuable cards, soon. KVNU Newstime is 740.
