I believe this is from an issue of Bantha Tracks. Although the sketches are legit, The whole story about filming in Death Valley is not found anywhere else and this Hal guy is pretty much now believed a liar.

This is amazing because I believe I met Hal at a local collectibles show. One booth had a little person (dwarf, I'm trying to be politically correct) signing autographs with a Jawa photo. I asked his name, which I don't recall, and who he played.

I then asked if there were any deleted scenes he was in. He described this exact scene! I knew every aspect of A New Hope including the filming and figured this had to be a lie but I just shook my head and said nothing. I have thought for years that this man was lying and that he was trying to make money off being a little person and signing autographs as a jawa. Now it's confirmed. Thanks!
