Quite a lot of signed new york posters have come up for sale
A bunch of unsigned ones as well but less
I'd estimate at least a dozen seperate signed NY posters have been posted on ebay (there were some double posts but I didn't count those)
And then probably 6 - 8 unsigned ones
Only seen 2 signed SF ones pop up but more will given time
anyone's guess as to which one is going to be truly rare
My guess is SF but by the number of people that attended it really shouldn't be
