how does this happen?

yes, i know that in 1957, topps did it to hank aaron, and in 1969 they did it to larry haney.  plus, 1979 saw topps do it to willie horton, and 20 years later, topps did it to aj hinch.  but how, in the year two thousand eleven, does topps reverse the negative on a duke snider card?

that's a card from 2011 topps tribute that i picked up recently.

it's not like the 'b' on the hat or the '4' on the back of the jersey are giveaways - this is duke snider, hall of famer.

still, the card is nice and shiny, so i am willing to overlook the reversed negative.  but if topps puts out a card of sandy koufax throwing with his right hand…

…it will have to be reaaaaaally shiny.
