From my 30 plus years in graphic design, advertising and printing the technology and ability is there to create a perfect counterfeit vintage card. Vintage stocks can also be found. It's an expensive and time consuming project to faithfully recreate it but someone might try now that the stakes are getting higher. Cost has generally been the prohibitive factor in the past to make it worthwhile in my opinion.
I agree it's getting pretty scary with all the doctoring out there and fakes getting by grading companies. Makes me feel better that most of my nice vintage cards came from family collections or friends and were collected mostly before 1980. I'm extremely careful when buying vintage now especially since I collect raw cards.
