@Glorfindel I remember that you have updated several posts with dead links to pictures, so I thought I might ask you.
specific-question images I have recently bumped this question: interlacing roots/eigenvalues results and modern analogues. It contains a broken link to an image. Is there some way it could be recovered?
The only idea I had was to check the snapshot in the Wayback Machine. Since I do not see anything there, I doubt that there is chance to find it somehow. (But I have at least asked, in case somebody can think of another possibility.)

Is there any relation between these theorems on interlacing roots? The roots of $f(x), f'(x)$ interlace (if all the roots of $f(x)$ are real and have real coefficients). The eigenvalues of an $n \times n$ matrix $A$ and it's minor $n-1\times n-1$ matrix $A_{ii}$ interlace (is a real symmetric m...

It seems that the OP has been inactive for some time, so a new version of the picture is unlikely to come from him, either.
