Be really careful with this one, folks. It's a unicorn of sorts, and the pressure to reprint it is obvious. If you find an authentic copy, you're looking at not a penny less than $3500 these days, if not more. It is, to my knowledge, the rarest of all the Matrix onesheets.
I went to my local poster shop and they did have this poster, but the owner wasn't sure if it was a reprint.
