3301 "Welcome" from subreddit - original picture

[ghost]

So there was this subreddit (https://www.reddit.com/r/a2e7j6ic78h0j) which 3301 used in one of their puzzles.
They posted a welcome picture (https://www.reddit.com/r/a2e7j6ic78h0j/comments/o3hoi/welcome/) containing their pgp signature if you outguess it.
So I found the original picture of it, by just reverse image-searching it on Bing - https://momza.blogspot.com/2011/04/house-hunting-with-slingshot.html
If you trust the blogpost date, the post is from April 2011 & therefore posted way before 3301's puzzle

Wow man, where did you find these materials? I think Cicada can use these images for their materials, however, I guess Cicada 3301 is over. I think the author of this repository must upload you said this material: https://www.reddit.com/r/a2e7j6ic78h0j
