From 45 years ago...

the Marvel comic book "Tales of Suspense",
March 1963 issue:

the complete origin story by Stan Lee: Anthony Stark's
trip to VIETNAM that led into the creation of Iron Man!!!

>>> just click on the pix and use the "zoom in" option
to see the pictures comic book size,
and check how closely the movie
stayed true to the original story.

thanks again, jon favreau!!!
