Forum:KB:Creator of First Star Wars Poster?

So I was browsing around earlier and came across this here - Don Ivan Punchatz while looking at the Memorial of deceased actors, artists, and authors. It claims that he drew the first-ever Star Wars film poster. However, first off, in the Star Wars work section in his infobox, it says that he did a poster for The Empire Strikes Back, which definitely is not the first Star Wars film. Secondly, if he did do the first ever Star Wars poster, how come we don't have a picture of it anywhere? I'm very curious about this poster - I always thought this one by Tom Jung, was the original.
