i really don't know why topps has been unable to put vin scully on a non-autograph card. i used to think that he wouldn't allow the use of his likeness, and that is why we got cards from topps of ernie harwell, bob sheppard, and even joe buck, but not vin. however, fleer put him on a card (with steve garvey) in 2004, and panini put him in their 2012 and 2013 cooperstown releases earlier this decade. i don't think topps put vin on a card until 2016 with their transcendant and mint releases - both of which were low-numbered autograph issues.
there have been good reasons in recent years to give vin a card - he finally retired following the 2016 season after 67 years in the booth and he was given a spot on the dodgers' ring of honor during the 2017 season (and helped throw out the first pitch prior to one of the 2017 world series games) - but topps has fallen short.
i was happy to find a 2017 leaf national sports collectors convention card recently
i picked up a magenta printing plate while i was at it
