Packer Pennant

Here is a scan of my oldest football card which is from the 1959 Topps set...and not surprisingly it's a Packer card...It's a little weird that the card is black and yellow rather than green and yellow.

The back is equally puzzling as the card delves into the supernatural with their "Magic Answer" quiz question. You can vaguely make out the answer that's hidden there but I don't want scratch it and destroy the card.

The answer will remain a riddle wrapped in an enigma.
