It took me a few years to consider registration on an equal playing field corners, surface, centering and the like.  However, I recently bought a 100% focused '57 Clemente lately and it brought to light what was "wrong" with my other one. Registration is now an essential component to a card with "eye appeal" in my book.  My only problem is that I have go back thru my '57s and replace all the blurry cards with sharp corners 

  BTW--Does anyone know when Topps corrected this issue?  And also, which set do you think suffers the most from this flaw in vintage cards? '57 is my vote...
