Who are the top 10 living vintage BB card experts?

[ethicsprof]

Phone conversations over the years with Jon Canfield and Ted Zanidakis have taught me a great deal about tobacco packs,boxes,pouches,
tins and the cards associated with them(JC)---and various aesthetic nuances associated with the T206s(TZ). My acquisitions would have been
greatly lacking without the help of these two.
The writings of Lipset have been critical to my knowledge of type collecting.
And the Net 54 community of scholars taught me the Gestalt...that the whole
of our knowledge has become greater than the sum of the individual parts.
all the best,
