Anecdote: In 2022, while visiting San Francisco, I had the chance to explore the campus. Wandering through the quiet, empty halls of the summer buildings, I was just about to leave when I unexpectedly came across Knuth's office [1]. I had to do a double take—it was surprisingly small for someone of his stature. Yet, in a way, it felt perfectly fitting, a reflection of his unassuming nature.
It's public knowledge that he's a prof at stanford and publicly available directories can lead you to his office. Not to mention that he's famous enough that this is almost certainly not the first time someone shares a photo like this.
If it was a photo of his home I'd understand but this is essentially public knowledge.

About the checks: I have not 1 but 2 checks. Small typos, nothing big: but wonderful to have these two documents.
