Mickey Mantle’s two sons got to know a little about the sports memorabilia industry when they’d travel to card shows with their father. Watch an on-camera interview with the folks at Topps.

Topps has ‘retired’ the number 7 from its baseball card sets. The Mick helped propel sales of baseball cards when the company began competing with Bowman in 1952.

Topps recently sat down with Mickey Mantle’s two sons for an interview you can watch below.

Be in for a shock, though. David Mantle is the spitting image of his Dad.
