Two American-published Akira poster-zines.

The first Akira Poster-Zine Magazine #1 is by Janus Publications, a first printing
 with glossy cover. Since the magazine is a folded poster the folds are apparent
and can be seen below.
As well as being a poster (standard poster size) of Kaneda on his cycle at the
Stadium, it also contains information about Otomo and the Akira movie.

I have little info about the second zine. It's another poster-zine released in the US
in around the late 1990's with a cover price of US$3.95
