My guess is..... most of the cel dealers collect
or had collected cels themselves and they got
their stuff from japan.
Cel collectror are all the same, if one show is
very popular in japan, it would be so in the
states also. If many people in japan are after
special scene or character, american cel
collector would do also.
Unless you have a dream cel from very very
unpopular show, like me, there are many
people who want the exact cel. I am still
looing for my dream cel, I posted here several
times but no reply, asked mandarake japan
but they don't have anything in stock. I never
see my dream cel in any dealer's site.
