My whole view on the moon landing shifted after I found my grandpa's 1969 newspaper with a weird printing error in the photo caption.

I was looking at the front page from July 21, 1969, and the caption under the 'lunar surface' shot read 'simulated environment' for a split second before the ink smeared, which made me dig into how newspapers actually received and printed those first images. Has anyone else found a weird physical clue like that in old media?
