Ted ZanidakisAfter having completed one T206 set (-Wagner & Plank) and
now working on a 2nd set (having 460 cards), I have never
seen any deviation regarding the known catalogued backs.
The Mark Peavey T206 book has a neat checklist of all the
back permutations. And, it was published in 2001, so it is
a great reference.
