This picture was also used in an article after 911. I know because I referenced the photo and the article early (don't know which board) when I was making an appeal to anons to try and start the patriotic wave (like after 911). I am certain of this but I I think the 911 article has now been scrubbed or buried.
The article was about Americans putting flags out (remember? they hung on houses, cars, businesses, office windows). It talked about how Americans stood in lines three hours long to buy flags that were back ordered for weeks.
