Apparently there are still some surprises to be discovered in old baseball cards.
It's not quite the yellow letter Mantle.
It's not even the 1979 Topps Bump Wills 'Blue Jays' or the 1989 Fleer Billy Ripken 'FF'.
However...those who appreciate the idiosyncrasies of vintage baseball cards will be interested in a printing variation that has been unveiled on Ron Fairly's 1961 Topps, some 47 years after it first popped out of wax packs.
There's a little green bleed to the color on the back in some cards--none in others. Here's a look at the variation and a little background behind the latest addition to your master set checklist from Beckett.com.
